Automotive Ignition & Door Locks

Shop automotive ignition locks, door-lock cylinders, lock sets, service packs, ignition switches, housings, and professional repair tools at Noble Key Supply. This collection includes replacement components for a wide range of domestic, Asian, and European vehicle applications.

Available products include coded and uncoded locks from ASP, specialized LockTech service tools, and additional automotive lock components from Noble Key Supply. Compare the vehicle information, lock position, keyway, part number, and included hardware before ordering.

Replacement Automotive Locks

Vehicle locks can become difficult to operate because of worn wafers, damaged keys, contamination, attempted theft, broken components, or previous repairs. Replacing or rebuilding the affected cylinder can restore reliable mechanical operation.

This collection includes products for several automotive lock-service needs:

• Ignition-lock cylinders
• Door-lock cylinders
• Coded replacement locks
• Uncoded service packs
• Complete lock sets
• Ignition switches
• Ignition-lock housings
• Shear-head bolts
• Removal and reset tools
• Replacement clips and hardware
• Other application-specific components

Automotive lock parts are highly application-specific. Verify the complete listing before disassembling the vehicle or preparing the replacement.

Automotive Ignition-Lock Cylinders

The ignition-lock cylinder is the mechanical component that accepts and turns the key. Depending on the vehicle, it may operate separately from the electrical ignition switch or be installed as part of a larger steering-column assembly.

Ignition-cylinder problems may include:

• A key that will not turn
• A key that binds during rotation
• Excessive movement inside the cylinder
• A key that can be removed in the wrong position
• Worn or damaged wafers
• A broken key lodged inside the lock
• A cylinder damaged during an attempted theft
• A replacement key that operates the doors but not the ignition

Proper diagnosis is important because similar symptoms can also be caused by a worn key, steering-lock pressure, an electrical switch problem, or a damaged housing.

Automotive Door-Lock Cylinders

Door-lock cylinders provide mechanical access when a remote or proximity key is unavailable. They remain important even on vehicles primarily operated through electronic entry.

Available door-lock products may include:

• Driver-side door locks
• Passenger-side door locks
• Coded door cylinders
• Uncoded service packs
• Locks with model-specific arms or pawls
• Application-specific retaining hardware
• Replacement cylinders for damaged or missing locks

Driver- and passenger-side locks may differ. Verify the listed position, orientation, attachment design, and included components.

Coded Automotive Locks

A coded lock is assembled to an existing key code or supplied in a predefined configuration, depending on the product. Coded cylinders can reduce the amount of bench work required before installation.

Before ordering a coded lock, confirm how the product is prepared and whether it is intended to match an existing vehicle key. Some listings described as coded may still require additional verification or adjustment for the specific application.

A replacement lock should be tested with the correct mechanical key before installation whenever possible.

Uncoded Lock Service Packs

An uncoded service pack allows a locksmith to configure the cylinder for the required key. These products are useful when the new ignition or door lock must match the vehicle’s existing mechanical key.

An uncoded pack may contain:

• Lock cylinder
• Wafers or tumblers
• Springs
• Retainers
• Face cap
• Pawl or operating arm
• Installation hardware
• Other application-specific parts

Contents vary. Some service packs require reuse of an original pawl, clip, face cap, or other component. Review the notes in the product listing before removing the original lock.

Ignition Service Packs

Ignition service packs provide parts required to rebuild or replace compatible ignition cylinders. They may be supplied coded or uncoded and can differ according to the ignition face, key system, housing, and production year.

Some Ford ignition applications, for example, distinguish between thumb-turn and key-turn face-cap designs. Similar cylinders may not interchange between those configurations.

Check:

1. Vehicle year, make, and model
2. Ignition design
3. Keyway and number of cuts
4. Face-cap style
5. Part number and supersessions
6. Coded or uncoded condition
7. Components that must be reused

These distinctions can determine whether the replacement fits and operates correctly.

Door-Lock Service Packs

Door-lock service packs provide the cylinder and related components needed to repair a compatible vehicle door lock. Some packs are uncoded and must be assembled to match the vehicle key.

Certain listings specify that the original pawl or linkage component must be reused. Inspect the original hardware before beginning the repair to ensure it is still serviceable.

Confirm whether the pack is for the left or right side and whether it includes the required clip, retainer, gasket, and operating arm.

Complete Automotive Lock Sets

A complete lock set may include multiple cylinders intended for the same vehicle. Depending on the application, a set can contain the ignition lock, door locks, trunk lock, or other mechanical components.

Lock sets can be useful when:

• Several cylinders are damaged
• The vehicle contains mismatched locks
• An attempted theft affected multiple components
• The owner wants one mechanical key for all locks
• Individual cylinders are no longer practical to repair

Review the included locks carefully because the contents of each set vary.

ASP Automotive Locks

ASP is the primary automotive lock brand represented in this collection. ASP produces ignition cylinders, door locks, coded locks, uncoded service packs, lock components, and related replacement hardware for numerous vehicle applications.

ASP part numbers often begin with references such as:

• C-series for ignition-related components
• D-series for door-lock applications
• LC references for lock cylinders
• DL references for door-lock service packs
• F-series for fasteners and related parts

Use the full ASP number and any listed alternate numbers when checking compatibility.

Ford Ignition and Door Locks

Ford applications in the collection include ignition cylinders, eight-cut service packs, door-lock service packs, and related components.

Ford vehicles may use different ignition-face designs, keyways, and cylinder configurations across the same general model range. Some products specifically exclude thumb-turn ignitions, while others require that design.

Check whether the listing calls for:

• Eight-cut or another key system
• Thumb-turn ignition
• Key-turn face cap
• Coded or uncoded cylinder
• Reuse of the original pawl
• A particular alternate part number

These details should be confirmed before ordering.

GM Ignition Locks

Chevrolet, GMC, Buick, Cadillac, and other GM vehicles have used several ignition-cylinder systems. Available products may include conventional coded locks, sidebar service packs, HU100 components, newer ignition service packs, and specialized removal tools.

HU100 applications can vary by vehicle platform and lock generation. Match the lock and service components to the vehicle rather than relying on the keyway name alone.

Some ignition-removal tools are designed for particular service conditions and require professional training. Follow the equipment manufacturer’s application information.

Honda and Acura Ignition Locks

Honda and Acura applications may include coded four-track ignition cylinders and specialized reset tools. Four-track locks require a compatible high-security key profile and application-specific cylinder.

Certain Honda ignition assemblies can develop spindle or plunger alignment problems during service. LockTech reset tools are designed for specified versions of these assemblies.

Confirm whether the vehicle requires the V1 or V2 tool and whether the selected ignition cylinder matches the production year and key system.

Honda Door Locks

Replacement door locks are available for select Honda vehicles, including model- and side-specific applications. A listing may identify a driver-side or left-hand door lock and specify whether the cylinder is coded.

Do not assume that the opposite-side lock is interchangeable. The housing, pawl, linkage, and mounting orientation may differ.

Toyota Ignition Cylinders

The collection includes coded Toyota ignition cylinders for supported vehicle applications. Toyota has used numerous edge-cut and high-security keyways, making exact identification necessary.

Confirm the ASP part number, vehicle coverage, key profile, ignition design, and coded status. If the vehicle’s door and ignition use different keys, determine whether a previous lock replacement has occurred.

Dodge, Chrysler, Jeep, and Ram Locks

Available Stellantis-related products may include uncoded ignition-cylinder service packs and other model-specific lock components.

These vehicles have used several mechanical and electronic ignition designs, including traditional key cylinders, FOBIK-style modules, and push-button systems. Make sure the vehicle actually uses the mechanical ignition cylinder represented by the listing.

Volkswagen Ignition Components

Volkswagen products may include ignition-lock housings and electrical ignition switches in addition to mechanical cylinders.

A housing, switch, and lock cylinder perform different functions:

• The lock cylinder accepts and turns the key.
• The housing supports the cylinder and may contain steering-lock components.
• The ignition switch translates mechanical movement into electrical operation.

Diagnose which component has failed before selecting a replacement.

Ignition Switches and Lock Housings

A vehicle that accepts and turns the key but does not power the correct electrical circuits may have an ignition-switch problem rather than a damaged lock cylinder.

A key that will not rotate can indicate a mechanical cylinder, steering-lock, housing, key, or alignment issue. Replacing the wrong component may not resolve the symptom.

Check wiring connections, mechanical movement, part numbers, and vehicle-specific service information during diagnosis.

Ignition Shear-Head Bolts

Shear-head or breakaway bolts secure ignition housings and related steering-column components on certain vehicles. Their heads are designed to separate at a specified torque during installation.

The collection includes standard-thread and reverse-thread versions for compatible applications. Thread direction must be confirmed before removal or installation.

Using the wrong bolt can damage the housing or threaded mounting point. Review the listing and vehicle service information carefully.

Automotive Lock Removal Tools

Specialized removal tools may help trained locksmiths and technicians service compatible ignition cylinders. These tools are application-specific and should only be used on the systems listed by the manufacturer.

Available products may include:

• HU100 ignition-removal tool sets
• Honda ignition-reset tools
• Broken-key extractors
• Cylinder-specific removal tools
• Related professional service equipment

Confirm the tool version, keyway, lock position, and supported vehicle before purchasing.

Broken-Key Extraction Tools

A broken key lodged inside an ignition or door lock may prevent normal operation. Extractor tools are designed to help technicians remove fragments from compatible keyways.

The correct approach depends on:

• The depth of the fragment
• Whether the key is turned
• The condition of the wafers
• Damage inside the keyway
• Access to the cylinder
• Whether the cylinder can be removed safely

After extraction, inspect the lock and the remaining key. A worn or binding cylinder may require repair rather than another copy of the damaged key.

Matching the Automotive Keyway

The replacement cylinder must use the correct mechanical keyway. Vehicles from the same manufacturer can use multiple edge-cut and high-security systems.

Keyway details may include:

• Blade profile
• Groove configuration
• Number of cuts
• Track design
• Code series
• Test-key reference
• Compatible Lishi reference

Match the replacement lock to the vehicle and the key that will operate it.

Matching Door and Ignition Keys

When practical, locksmiths may configure a replacement cylinder so the existing vehicle key continues to operate both the doors and ignition. This avoids requiring the driver to carry separate mechanical keys.

Before coding the new cylinder, confirm that the existing key reflects the correct factory code and is not excessively worn. Cutting a fresh key by code may provide more accurate operation than using a heavily worn key as the reference.

Included and Reused Components

Some service packs are complete, while others require parts from the original lock. Components that may need to be transferred include:

• Pawl
• Tailpiece
• Operating arm
• Face cap
• Retaining clip
• Switch
• Housing
• Gasket
• Electrical connector
• Mounting hardware

Read the product notes carefully and inspect the original lock before disassembly.

How to Choose the Correct Automotive Lock

Before ordering, verify:

1. Vehicle year, make, and model
2. Production date or VIN range
3. Ignition or door-lock position
4. Driver or passenger side
5. Mechanical keyway
6. Number of cuts
7. Thumb-turn or key-turn design
8. Coded or uncoded configuration
9. ASP or manufacturer part number
10. Alternate and superseded part numbers
11. Included components
12. Parts that must be reused
13. Standard or reverse-thread hardware
14. Professional service-tool requirements

Checking these details helps prevent fitment problems and incomplete repairs.

Professional Installation and Testing

Automotive lock replacement may involve steering-column components, electrical switches, door panels, linkages, trim, and security hardware. Installation should be completed by a qualified locksmith or automotive technician.

After installation, test:

• Smooth key insertion and removal
• Rotation through every intended position
• Door locking and unlocking
• Ignition accessory and run positions
• Engine cranking, when applicable
• Steering-lock operation
• Key removal position
• Existing remote functions
• Transponder authorization

A mechanical lock replacement does not automatically program a transponder key or remote.
