Land Rover Defender L663 key replacement, spare keys & all-keys-lost – UK & USA

Need a Land Rover Defender L663 replacement key near you? We supply, cut and program Land Rover Defender L663 smart keys anywhere in the UK and across the USA – a spare key while you still have one working, or a full all-keys-lost service when every key is gone. All programming is done at your home, work or roadside with genuine JLR-level tooling: no main-dealer wait and no recovery truck. Every key carries a 12-month warranty.

Which key does your Land Rover Defender L663 use?

From 2020 onwards the Land Rover Defender L663 uses a keyless smart-proximity key (passive entry, push-button start). UK cars run on 433 MHz and later Defender-generation cars add UWB ultra-wideband ranging; the key talks to the RFA / keyless module, so a replacement or spare must be programmed to the car over the diagnostic port.

Compatible RFA / keyless part numbers we stock

We hold new and virgin RFA (Remote Function Actuator) modules and matching smart keys for the Land Rover Defender L663 across 2020 onwards, in both UK 433 MHz and USA 315 MHz specification, including:

• JPLA-19H440-DE (LR099141 / T4K6115) – 3-plug RFA PEPS
• JPLA-19H440-BE – 2-plug RFA PEPS
• J9C3-19H440-DF / -BF (J9C2798) – RFA PEPS
• K8D2-19H440-AB (J9C2796), -AC (LR117928 / T2H38587) – 1-plug RFA
• K8D2-19H440-BB / -BC (LR117932 / T2H38589) – 2-plug RFA PEPS
• M9R3-19H440-BD / -BE – latest 1-plug RFA PEPS

Not sure which module your car has? Send us the VIN and we will confirm the exact RFA part and frequency before we travel.

How a Land Rover Defender L663 key job works

We read the car, add the new key to the keyless module and verify passive entry and push-button start before we leave. A spare key is typically a 30–45 minute job; an all-keys-lost job takes a little longer because the system has to be re-secured to the new key set. Everything is done at your home or workplace.
