We support BMW models from early E-series through F-series and the latest G-series, including electric and hybrid models. That covers popular vehicles across Dartford like the 1 Series, 3 Series, 5 Series, X1, X3, X5, 7 Series, Z4, and i3/i4, as well as M Sport variants.
BMW Key Systems We Work With
BMW has used various immobiliser and key technologies over the years. Our team is trained and equipped for them all:
- Diamond and rectangular remote keys for earlier E-series
- CAS (Car Access System) 1–4 modules with transponder keys
- FEM/BDC systems on later F/G-series with smart/proximity keys
- Comfort Access and keyless entry programming
- Push-to-start and proximity key replacement for modern models
- High-security laser cut BMW key blades and sidewinder profiles
If your BMW displays messages like “Key not detected”, “Remote control not working”, or shows a key symbol on the dash, we can diagnose and repair the issue quickly using BMW-specific tools and dealer-level software.
How Our BMW Auto Locksmith Service Works
We make BMW key and lock problems straightforward to resolve, without the hassle of a main dealer visit.
- Assessment and Security Check
- We’ll confirm your BMW’s model, year, and VIN, verify ownership, and assess the fault.
- Common issues include key fob failure, immobiliser sync loss, or a flat vehicle battery causing key errors.
- Non-Destructive Entry Where Possible
- Locked out? We use specialist lock picks and access tools designed for BMW locks to open your vehicle cleanly and without damage wherever possible.
- In rare cases where minimal drilling is necessary (e.g., failed locks), we will explain options and obtain approval before proceeding.
- Diagnostics and Programming
- We connect to the vehicle via OBD2 using dealer-level diagnostics to identify immobiliser or central locking faults.
- For FEM/BDC or CAS module issues, we carry out safe programming or, if required, EEPROM-level work to pair new keys correctly and restore functionality.
- Key Cutting and Pairing
- We cut laser cut car keys precisely to your lock code.
- Transponder key programming, smart key programming, or proximity key replacement is completed on-site.
- We test remote central locking, Comfort Access, and push-to-start to ensure everything works as it should.
- Final Checks, Guidance, and Warranty
- You’ll receive your working BMW key(s), advice on battery care and safe storage, and details of our warranty on workmanship and keys.

FAQs: BMW Keys And Locks
Can you replace a lost BMW key without the original?
Yes. We can create and program a new BMW key without the original by verifying ownership and using dealer-level diagnostics. Depending on model and year, this may involve CAS or FEM/BDC programming and, in some cases, EEPROM work. Our mobile service covers Dartford and all DA postcodes.
My BMW says “Key not detected.” What should I do?
First, try holding the key next to the steering column or designated backup start point (varies by model) and replace the key battery if available. If the message persists, call us. We’ll test the key, check the vehicle battery and aerials, and reprogram or replace the key if required.
Do you offer non-destructive BMW vehicle unlocking?
Yes. We use specialist BMW-compatible tools for non-destructive entry wherever possible. If a lock has failed internally, we will discuss options before any minimal drilling and carry out neat, professional repairs.
Can you program BMW Comfort Access and smart keys?
Absolutely. We handle smart key programming, Comfort Access pairing, and proximity key replacement for modern BMWs using secure, dealer-level methods.
How long does BMW key replacement take?
In many cases, a replacement or spare BMW key can be cut and programmed during a single visit. Timing varies by model, key type, and immobiliser system. We’ll give you an accurate timescale when you call.
Is a mobile auto locksmith cheaper and faster than a BMW dealer?
Often, yes. There’s no towing, we come to you, and we can provide same-day assistance in many cases. For more on factors affecting cost, see our auto locksmith prices in Dartford.
