Peugeot Key Replacement & Programming — Mobile Service Across Somerset & Wiltshire
From a BSI fault that kills every key at once to an e208 that has simply gone to sleep — we diagnose before we replace.
Peugeot key problems have an unusual signature: quite often the key is fine and the car's central computer is the thing refusing to listen. Knowing that early saves replacing perfectly good keys.
We cover both the long-running petrol and diesel range and the current electric models, on-site across Somerset, Wiltshire and Dorset.
Older and shared Peugeot key systems we work on
One component dominates fault-finding across most of the range, and it is not the key.
- Across the 206, 207, 208, 307, 308, 407 and Partner, the BSI — the central body control computer — is the most significant failure point
- The BSI stores the transponder codes, so its failure can leave the car completely unresponsive to any key
- Water ingress is a common cause, as the unit is commonly mounted near the passenger footwell
Current Peugeot models we work on
On the current electric range the most commonly reported keyless issue is a behaviour rather than a breakage.
- On the current electric e208, keyless entry can enter a 'sleep' state after the car has been left
- The car then needs waking — via the boot release, for example — before it responds normally
- Because it clears once the car is woken, it is easily mistaken for a failing key
What happens on the visit
We check whether the car is reading the key at all before doing anything else, because on a Peugeot that single answer separates a key job from a BSI job. Keys are cut and coded at your vehicle where that is what the fault calls for, and everything is tested before we leave.
Common questions
- My Peugeot is completely unresponsive to any key — could that be the BSI?
- It could. Across the 206, 207, 208, 307, 308, 407 and Partner, the BSI — the central body control computer — is the most significant failure point. It stores the transponder codes, so when it fails the car can be left completely unresponsive to any key. Water ingress is a common cause, as the unit is commonly mounted near the passenger footwell.
- Why does my e208's keyless entry not respond first thing in the morning?
- On the current electric e208, the keyless entry system can enter a 'sleep' state after the car has been left standing. The car then needs waking — using the boot release, for example — before the keyless system responds normally again.
- Can a locksmith fix a BSI fault, or does it need a dealer?
- We diagnose the BSI side on-site and tell you honestly what we can and cannot resolve at your vehicle, rather than replacing keys on a guess. Because the BSI holds the transponder codes, confirming whether the fault sits there or with the key is the essential first step either way.
