Your Local BMW Key Specialist
I'm Dean — a specialist mobile auto locksmith based in Honiton with over 15 years of experience, including extensive work on BMW vehicles. BMW security is more sophisticated than most makes, built around the CAS (Car Access System) on older models and the newer FEM/BDC (Front Electronic Module / Body Domain Controller) on F and G-series vehicles. Whether you've lost your BMW keys, need a spare BMW key cut and programmed, or your BMW won't recognise its key, I carry professional AUTEL and Xhorse equipment built for the full BMW range.
Unlike a main dealer, I come to you — home, workplace, car park or roadside — and complete the BMW key programming on-site. There's no need to recover the vehicle to a dealership or wait days for an appointment, and the cost is typically well below dealer pricing.
BMW's CAS system (and FEM/BDC on later models) pairs each key electronically to the car through an encrypted handshake — one of the more advanced immobiliser systems in the industry. My AUTEL diagnostic equipment communicates directly with these modules, giving me the same capability as a BMW dealership, brought to your door. For advice on protecting your BMW against keyless relay theft, the AA has a practical guide to keyless car security.
BMW Key Types We Work With
BMW has used several key and entry technologies across its range over the years. I work with all of them:
BMW Diamond Keys
The classic diamond-shaped remote keys used across many 1, 3 and 5 Series models — named for their distinctive shape.
BMW Comfort Access Keys
Proximity smart keys that unlock and start without pressing a button, common on newer 3 and 5 Series.
BMW Display Keys
The advanced touchscreen key fobs on newer premium models including the 7 Series and X5.
BMW Slot Keys
Keys inserted into a dashboard slot to start, common on mid-era E60/E90 models.
BMW CAS Transponder Keys
Chip-coded keys that pair with the Car Access System immobiliser on older models.
BMW FEM/BDC Keys
Keys for F and G-series vehicles using the Front Electronic Module or Body Domain Controller.

Our BMW Auto Locksmith Services
BMW Key Replacement (Lost Keys)
Lost all your BMW keys? No original needed. Using your VIN and CAS or FEM/BDC immobiliser data I create a complete replacement key from scratch on-site, then delete the old keys for security. See lost car keys.
Spare BMW Keys
A spare BMW key is the best way to avoid a future lockout. I cut and programme spares for all BMW models on-site — diamond keys, Comfort Access and slot keys — far cheaper than an emergency replacement later.
BMW Key Programming
BMW key programming via the CAS and FEM/BDC modules. My AUTEL equipment programmes new keys, syncs fobs and resolves coding faults — the same capability as a dealership, at your location.
BMW Comfort Access & Smart Keys
Full programming of BMW Comfort Access proximity keys and Display keys. These use advanced encryption but the process is the same — read the immobiliser, programme the new smart key, test and hand over. See transponder keys.
BMW Key Fob Repairs
A BMW key fob that has stopped working often just needs a new battery, button repair or reprogramming. I diagnose and repair before recommending a full replacement.
BMW Broken Key Extraction
Snapped a BMW key in the door or barrel? Don't dig it out. I safely extract the broken blade and cut a fresh working key on-site.
Common BMW Issues We See
Across thousands of BMW callouts, certain faults come up again and again. If you're experiencing any of these, I can help:
Recent BMW Job — Plymouth
BMW 3 Series — Lost Only Key
A customer lost the only key to a 2016 BMW 3 Series (F30) parked in Plymouth. BMW's CAS security makes this a specialist job — the module has to be read and a new key paired electronically. I attended the same day, gained non-destructive entry, accessed the CAS module, programmed a new diamond key on-site and deleted the lost key from the system. The customer was driving again that afternoon, well below the main dealer quote and with no recovery vehicle required.
Main Dealer vs DB Car Keys
For most BMW key and lock jobs, a mobile specialist saves you time and money compared with a main dealer:
| Main Dealer | DB Car Keys | |
|---|---|---|
| Getting the car there | ✗Recovery often needed | ✓We come to you |
| Waiting time | ✗Days, parts ordered | ✓Same day |
| Pricing | ✗Higher | ✓Typically lower |
| Where the work happens | ✗Workshop visit | ✓Mobile, at your location |
| Availability | ✗Business hours | ✓24/7 emergency |
What BMW Customers Say
“Lost the only key to my BMW 3 Series and the dealer wanted a fortune plus a two-week wait. Dean came to me in Plymouth, sorted a new key the same day for far less. Brilliant service.”

Frequently Asked Questions — BMW
Yes. Using your VIN and CAS or FEM/BDC immobiliser data I create a complete new BMW key from scratch at your location. All old keys are deleted from the system for security.
Yes — even though BMW security is more advanced than most makes, I access the CAS or FEM/BDC module through the OBD port, read the security data and programme a brand new key on-site with no original key present.
Yes. I programme BMW Comfort Access proximity keys and Display keys for models across the E, F and G-series range. Read the immobiliser, programme the new smart key, test and hand over.
CAS (Car Access System) is used on older E-series BMW models (E90, E60, E87 etc). FEM (Front Electronic Module) and BDC (Body Domain Controller) are used on F-series and G-series models respectively. Both require specialist diagnostic equipment to programme keys — I carry AUTEL tools capable of both systems.
BMW keys cost more than volume brands because the security is more complex. I give a confirmed price before I travel and am typically well below dealer pricing. Call 07830249408 with your model, series and year.
Yes. The X1, X3, X5 and the rest of the X-range are all within scope for key replacement and programming alongside the 1, 2, 3, 4 and 5 Series.
Yes. This is usually a CAS or FEM/BDC communication fault. I diagnose it on-site, resync the key or programme a replacement if the key has failed.
