Jaguar & Land Rover Remote Keys

Shop Jaguar and Land Rover remote keys for compatible vehicle key replacement and duplication jobs. Noble Key Supply carries dependable automotive keys for professional locksmiths, dealerships, repair facilities, and other automotive security specialists.

The current collection focuses on an aftermarket Paladin remote head key for supported Land Rover Discovery applications. This key combines the mechanical blade, immobilizer transponder, and remote-control functions within one convenient housing. Although the collection covers Jaguar and Land Rover remote keys as a category, available applications may change as inventory is updated.

Land Rover Discovery Remote Head Key

The available Land Rover Discovery remote head key is designed as an aftermarket replacement for compatible original keys carrying the N5FVALTX3 FCC ID. Its integrated construction provides the key blade and electronic components required for vehicle access, ignition authorization, and supported remote functions.

Current key specifications include:

• FCC ID: N5FVALTX3
• Transponder chip: ID73
• Frequency: 315 MHz
• Battery: CR2032
• Product type: Remote head key
• Condition: New aftermarket replacement
• Brand: Paladin

Always compare the replacement key’s identifying information with the customer’s original key and vehicle application data before ordering, cutting, or programming.

Quality-Tested Paladin Aftermarket Keys

Paladin keys are designed to give automotive professionals a reliable aftermarket option for common replacement-key applications. Each key is quality tested to help ensure dependable construction, consistent electronic performance, and accurate compatibility with the specifications listed on the product page.

A quality replacement key can help reduce avoidable programming problems, physical housing failures, and customer returns. Paladin remote head keys are intended to provide a professional finished product while offering an economical alternative to purchasing a replacement directly from a dealership.

Compatibility still depends on selecting the correct FCC ID, chip type, operating frequency, blade, and vehicle application. Quality testing does not make differently specified keys interchangeable.

What Is a Remote Head Key?

A remote head key places multiple vehicle-key components inside one integrated assembly. Depending on the application, it may contain:

• A mechanical blade for operating the ignition and door locks
• A transponder chip for communicating with the vehicle’s immobilizer
• Remote electronics for supported lock and unlock functions
• A replaceable battery that powers the remote transmitter

This design differs from a vehicle that uses a completely separate key and remote. It also differs from a proximity key, which may allow passive entry and push-button starting without inserting a blade into the ignition.

The correct replacement should match the type of key system originally used by the vehicle. A proximity key, standalone remote, and remote head key should not be treated as interchangeable simply because they are intended for the same vehicle brand.

Match the FCC ID Before Ordering

The FCC ID is one of the most important details to verify when selecting a replacement automotive remote key. It identifies the transmitter design and helps distinguish between keys that may have similar appearances but use different electronics.

For the currently available Land Rover Discovery remote head key, the listed FCC ID is N5FVALTX3. Compare this number with the customer’s original key, an approved compatibility reference, or reliable vehicle-specific programming data.

A visual match alone is not enough. Two remote head keys may use nearly identical housings while operating with different frequencies, transponder chips, button configurations, or electronic protocols.

Verify the 315 MHz Frequency

The operating frequency determines how the remote communicates with the vehicle’s receiver. The current Land Rover replacement key operates at 315 MHz.

Frequency requirements can differ according to vehicle model, model year, production market, and key-system version. A remote transmitting at the wrong frequency will not become compatible simply because it can be physically cut or because its housing resembles the original key.

Confirm the required frequency before beginning the job, especially when working with imported vehicles or applications offered with more than one electronic configuration.

ID73 Transponder Chip

The integrated ID73 transponder chip communicates with the vehicle’s immobilizer system. When the key is used, the vehicle must recognize the programmed chip before it will authorize the engine to start.

Cutting the blade allows the key to operate the matching mechanical lock, but it does not program the transponder. The ID73 chip must be correctly introduced to the vehicle using compatible diagnostic or key-programming equipment and the appropriate procedure for the application.

Programming requirements may vary depending on whether:

• A working key is available
• The job is an all-keys-lost situation
• Security credentials or codes are required
• The vehicle supports onboard procedures
• A dedicated programmer or diagnostic platform is needed
• Existing key data must be read or preserved

Review the procedure before starting so that the appropriate equipment, access credentials, and vehicle support are available.

Cutting and Programming Requirements

A complete remote head key replacement may require several separate services:

1. Confirm the vehicle, model year, FCC ID, chip, frequency, and blade compatibility.
2. Inspect the replacement key before making permanent modifications.
3. Cut the blade using a compatible key machine and the correct jaw, cutter, or adapter.
4. Program the ID73 transponder to the immobilizer system.
5. Pair or synchronize the remote functions when required.
6. Test the blade, engine-start authorization, buttons, and emergency access functions.

Transponder programming and remote pairing are related processes, but they may not always occur through the same procedure. A key can sometimes start the vehicle while the remote buttons remain inactive, or the remote may operate while the immobilizer portion has not been properly programmed.

Test every supported function before returning the completed key to the customer.

Confirm Vehicle Compatibility

Jaguar and Land Rover vehicles can use different key systems across generations, trims, markets, and production dates. Before ordering, confirm:

• Vehicle make and model
• Exact model year
• Original FCC ID
• Operating frequency
• Transponder chip type
• Blade profile
• Button layout
• Ignition type
• Original key style
• Programming-tool coverage

The current collection selection centers on a supported Land Rover Discovery remote head key application. Jaguar remote-key availability and additional Land Rover coverage may vary as products are added or restocked. Consult the individual product listing for the most current compatibility information.

A Professional Replacement for Lost or Damaged Keys

A compatible remote head key may be used to replace a lost, damaged, worn, or malfunctioning original key. It can also be used to create a spare key before an all-keys-lost situation occurs.

Keeping a properly cut and programmed spare can help vehicle owners avoid the added expense and inconvenience that often accompany complete key loss. For locksmiths and other automotive professionals, stocking the correct replacement keys can improve turnaround time and make it easier to complete eligible jobs without waiting for a dealer-ordered key.

Inspect the Key Before Cutting

Key blades and electronic keys generally cannot be returned after they have been cut, programmed, opened, or otherwise modified. Before beginning work:

• Verify all identifying numbers
• Check the button arrangement
• Confirm the blade profile
• Inspect the housing for shipping damage
• Verify programmer support
• Review the applicable programming procedure
• Confirm whether the job is an add-key or all-keys-lost situation

Completing these checks before modification helps prevent compatibility errors and protects both the technician and the customer.
