Two Defenders — Two Systems
The Land Rover Defender name spans two vehicles that have almost nothing in common from a key security perspective. The heritage Defender — produced from 1983 to 2016 — uses a traditional blade key with an RFID transponder chip. The new L663 Defender — launched in 2020 — is an entirely new vehicle using the most advanced key security in the Land Rover range. Telling us which Defender you have is the single most important piece of information when calling.
The heritage Defender uses a traditional blade key with RFID transponder chip and basic immobiliser. Key types evolved across production: 300Tdi (pre-1999) — earlier key system, no chip on very early models; Td5 (1999–2007) — RFID chip introduced; 2.4 Puma TDCi (2007–2011) — updated transponder system; 2.2 TDCi Puma (2012–2016) — final production key. All heritage Defender key types are covered — blade cutting, transponder programming and remote fob pairing where applicable.
The new L663 Defender (2020–present) uses the advanced KVM (Key Vehicle Module) with UWB (Ultra-Wideband) keyless proximity throughout its entire production run — 90, 110 and 130 body lengths all use the same system. This is the same advanced key architecture as the Range Rover L460 and Range Rover Sport L461 — requiring IDS/SDD-compatible specialist platforms for all key operations. The Defender V8 uses the same advanced KVM + UWB as all other new Defender variants.
JLR Key covers both Defender generations for all key services on-site across North Wales. DPF cleaning and ECU remapping are also available for Defender diesel models.
Defender Models & Key Types
All heritage and new Defender variants covered. The body length (90, 110, 130) does not affect the key system — it is the vehicle generation that determines the security architecture.
90, 110, 130 and V8: All new Defender body lengths — 90, 110 and 130 — use the same advanced KVM + UWB key system. The Defender V8 (525ps) and Defender Octa (635ps) also use the same advanced KVM + UWB as all other new Defender variants. The body length and engine choice have no effect on the key security architecture.
