How We Work With Mercedes Security Systems
Mercedes-Benz immobiliser systems are sophisticated, often using IR smart keys and start authorisation modules integrated with the ECU and steering lock. Our process is designed to resolve issues efficiently while protecting your vehicle’s electronics:
-
Assessment and Diagnostics
- We plug into your Mercedes with dealer-level diagnostics via the OBD2 port to read fault codes and security status.
- For certain older or specialist cases, we may use EEPROM techniques to access immobiliser data safely.
-
Non-Destructive Entry
- If you’re locked out, we use non-destructive methods to open the vehicle wherever possible.
- Any rare need for drilling (usually only on severely damaged locks) is always discussed and approved before action.
-
Key Cutting and Coding
- High-precision cutting for laser and high-security blades where applicable.
- Key programming to your vehicle’s immobiliser, including remote functions and keyless entry.
-
Final Testing
- We verify door locking, boot release, remote range, start authorisation, and dash warnings before handover.
- We provide guidance on key care and options for a spare to minimise future disruption.

FAQs About Mercedes Keys and Locks
Can you program a Mercedes key without the original?
Yes. In most cases we can create and program a new Mercedes key without the original. We use dealer-level diagnostics, and for some models we may use EEPROM methods to securely access immobiliser data. This is done on-site, so you don’t need to tow your car to a dealer.
My Mercedes says “Key Not Detected”. What should I do?
First, try your spare key if you have one and replace the key battery. If the issue persists, it may be a smart key fault, antenna/ring issue, steering lock fault, or a start authorisation problem. We can diagnose with OBD2 and resolve by reprogramming, repairing the key, or addressing ESL/immobiliser faults.
Can you fix an electronic steering lock (ESL/ELV) fault?
In many cases, yes. We can diagnose ESL/ELV failures and offer repair or replacement options depending on the model. We’ll explain the most reliable and cost-effective route and handle coding so your car starts reliably again.
Do you use non-destructive entry on Mercedes?
Yes, we use non-destructive techniques wherever possible, using specialist tools suited to Mercedes locks. In very rare cases where a lock is damaged beyond recovery, we’ll discuss options and costs before proceeding.
How long does a new Mercedes key take?
Many replacements are completed the same visit. Timing varies with model, year, and whether all keys are lost. We’ll give you an accurate timeframe when you call.
Is this service cheaper than a Mercedes dealer?
Often, yes—especially when factoring time, towing, and the convenience of our mobile service. We provide transparent quotes up front. For more on value and factors, see our page on auto locksmith prices in Redhill.
