The original Range Rover Sport (L320) ran from 2005 to 2013 and shares much of its security architecture with the Discovery 3 and Discovery 4. The platform is encrypted and tightly locked to JLR equipment, which is why most general locksmiths simply cannot help. The two real options are a main Land Rover dealership or AJ Auto. We cover every L320 model year from 2005 to 2013, attending your home, office or roadside anywhere in the UK. Same day service in almost every case, with no lock module replacement and no need to send the vehicle anywhere.
For an L320 spare key or a replacement for a damaged remote, we come to you and programme the new key on site. Our mobile workshop carries the proper diagnostic software for the platform along with genuine-specification remotes that fully support keyless start and the factory alarm. Existing keys keep working alongside the new one, the security module stays exactly where it is and there is no impact on the vehicle’s electronics beyond adding the new remote into memory.
For all keys lost we attend your location with the correct hardware already in the van, talk to the immobiliser directly, wipe the old key data and pair fresh remotes in a single visit. There is no recovery, no flatbed and no dealership wait. Most attendances are wrapped up in around an hour. Parts and programming are backed by a 12-month warranty, and the price is agreed before we leave the workshop so the figure quoted on the phone is the figure you pay on the day.
The L320 Range Rover Sport (2005–2013) uses a Hitag2 transponder system managed through the Body Control Module. New remotes must be authenticated and written to the BCM’s approved key list using manufacturer-level JLR diagnostic software — standard automotive key-cutting machines and generic OBD programmers do not support the L320’s proprietary security architecture. This means any professional key programming job requires a trained JLR specialist with the correct tools, which is exactly what our mobile service provides.
Our technicians carry L320-compatible smart key fobs and connect a JLR SDD diagnostic interface to your OBD port. The programming sequence reads the existing security token from the BCM, authenticates the new fob and adds it to the approved list. For all-keys-lost situations we perform a complete immobiliser reset, generate new security seeds and programme all fresh remotes together in a single encrypted session — no dealer visit required. L320 key programming typically takes 15 to 30 minutes for a spare key addition and 30 to 45 minutes for an all-keys-lost job.
How does Range Rover Sport (L320) key programming work and how long does it take?
The L320 uses a Hitag2 transponder paired through the Body Control Module. Our technician connects JLR diagnostic software to the OBD port, reads the current security token and writes the new remote into the approved key list. A spare key addition takes 15 to 30 minutes; an all-keys-lost reset and reprogram takes 30 to 45 minutes. The whole job is completed at your location with no recovery needed.
My L320 key fob buttons have stopped working but the engine still starts — can you fix this?
A fob that will start the engine but no longer operates central locking usually has a failed RF transmitter or a dead battery in the remote circuit. We can diagnose on site, supply a new remote body with the same transponder profile and programme it to your vehicle in a single visit. If the transponder itself has failed we carry replacement hardware that is compatible with the L320 BCM.
Can you programme a key for a supercharged or SVR-spec L320?
Yes. Performance variants of the L320, including the supercharged 4.2 and 5.0 models, use the same BCM-based key security system as standard L320 models. Programming procedure and timescales are identical regardless of engine specification. We carry stock suitable for all L320 variants in the van.
Do you cover callouts outside major cities for the L320?
Our mobile service covers England and South Wales, including rural areas and motorway locations. We travel to farms, business premises and residential addresses outside city centres. If you are in a remote location with an all-keys-lost L320, call us and we will confirm the nearest available slot rather than leaving you stranded.
Will a new key affect my L320’s security settings?
Adding a spare key does not alter any existing security configuration. We write the new remote into the approved list without touching alarm sensitivity, door lock timing or other BCM settings. In an all-keys-lost scenario where a full security reset is needed, we restore all security parameters to factory defaults as part of the same job.
Is there a warranty on L320 key programming work?
Yes. All parts and programming work carry a 12-month warranty. If a remote fails to operate correctly within the warranty period, we return to site and resolve the issue at no additional charge. The fixed price quoted by phone includes all labour and parts with no hidden call-out charges.
We also cover related Sport models. If you need a key for the second-generation Range Rover Sport (L494), the third-generation Range Rover Sport (L461), or the Range Rover (L322) which shares the same platform era, our mobile service covers all three alongside the L320.
