A Mercedes key carries several parts under one housing, the remote, the electronic part the immobiliser reads and a mechanical emergency key element. Which of those parts has failed or gone missing decides the work. Inta-Lock holds SERMI accreditation, and Keys By Post is offered for supported Mercedes models.
Matt is with you within the hour in Leicester, and the same day across Leicestershire. Calls are answered 24 hours a day, every day of the year, and a quote is agreed before work begins.
Mercedes Key Work Carried Out at the Car
Mercedes key work at the car covers the states below, and the method for each state belongs to its own service page.
- Replacement Mercedes key. A new Mercedes key is supplied, cut and programmed in place of one that is lost, stolen, broken or worn.
- No working Mercedes key. A key is produced without an original to copy, and missing electronic keys are removed from the immobiliser memory where the vehicle supports it.
- Spare Mercedes key. A second key is added to the car while the first key still starts it.
- Mercedes key programming. A supplied or replacement key is registered with the car, so the immobiliser reads it as its own.
- Locked out of a Mercedes. A Mercedes with the key shut inside is opened by non destructive entry.
- Mercedes van keys. Keys for Mercedes vans follow the van key service, with the van identified from its registration.
Support for a given Mercedes model and year is confirmed on the call, before Matt travels.
Mercedes Key Functions and the Route for Each
Five functions sit behind a Mercedes key, named here as the Mercedes owner manual names them, and each one has a route of its own.
| Mercedes function | What it does on the car | Route for the physical key | Where it is handled |
|---|---|---|---|
| Key in the ignition lock | On models with an ignition lock, the key is inserted and turned through its key positions to start the engine. | A replacement key is programmed to the car. Say on the call that the car starts with the key in the ignition lock. | At the car in Leicester, for supported models. |
| KEYLESS-GO with the Start/Stop button | On equipped models, KEYLESS-GO locks and unlocks the car and provides a start function, and the engine starts from the Start/Stop button. | A KEYLESS-GO key is registered with the car. Say on the call that the car starts from a button. | At the car in Leicester, for supported models. |
| Emergency key element | A mechanical part that is removed from the key and inserted again, and that locks the vehicle by hand. | Say on the call whether the emergency key element is still held. | At the car in Leicester, or through Keys By Post for supported models. |
| Immobiliser | The owner manual lists the immobiliser under protection against theft. The engine starts only with a key the car has registered. | A new key is registered, and missing electronic keys are removed from the immobiliser memory where the vehicle supports it. | At the car in Leicester, for supported models. |
| Remote door locking and Digital Vehicle Key | On a connected Mercedes with the service active, the doors lock and unlock from the manufacturer app. Mercedes also names a Digital Vehicle Key feature. | Neither is cut or programmed as a physical key. Each is managed through the digital setup Mercedes supports. | The Mercedes account of the owner. Inta-Lock works on the physical key, the locks and the immobiliser. |
The first two rows are alternatives, and the registration shows which one the Mercedes uses. The key route for the remaining rows follows from the part that is missing or faulty.

Call Matt on 0116 442 2084Mercedes Key System Names and Security Access
Mercedes uses its own names for key functions. KEYLESS-GO is the name for keyless locking, unlocking and starting on equipped models, and the emergency key element is the mechanical part of the key. Those two names, read from the owner manual or the key itself, tell Matt which Mercedes key system is in front of him.
Inta-Lock holds SERMI accreditation, and the scheme authorises access to security related manufacturer information where supported work requires it. SERMI approves and authorises independent operators for that access.
Advanced Diagnostics, Abrites, Autel, Xhorse and SPVG are used for automotive key programming and diagnostics. For supported Mercedes models there is a second route beside attendance, keys by post, and whether a Mercedes qualifies is confirmed on the call.
From First Call to Tested Mercedes Key
Five steps cover a Mercedes key job from the phone call to the test at the car.
- Ring 0116 442 2084. Matt answers the call and attends the job himself.
- Give the registration, the Mercedes model and the year, and say whether the car starts from the ignition lock or from the Start/Stop button.
- Say how many keys are left and where the Mercedes is parked. Support for the model is confirmed at this point, and the route is set, attendance or Keys By Post.
- Identity and authority to request the work are checked before key work begins. The V5C vehicle registration certificate and photo identification are common examples, and what applies is confirmed on the call.
- The Mercedes key is cut and programmed, then every function is tested with you beside the car, locking, unlocking and starting.
A quote is agreed before work begins.
Mercedes Ranges and Model Years on the Call
Mercedes key systems differ between ranges and between model years of one range. The current United Kingdom line runs from the A-Class and C-Class through the E-Class and S-Class to the GLA, GLC and GLE, with EQA, EQB, EQE and EQS electric models, and the Sprinter and Vito vans sit beside the cars.
The registration identifies the range, the model year and the key system in one step. Matt confirms from it whether the Mercedes is a supported model before he attends.

Related Mercedes Key Situations and Other Makes
Three Mercedes key situations hand their method to a service page, and two comparisons close the page.
A Mercedes With No Working Key Left
A Mercedes with no working key stays where it is parked, and a key is produced at the car for supported models. The method, from entry to the programmed key, is set out under lost car keys.
Where a key is lost or stolen, missing electronic keys are removed from the immobiliser memory where the vehicle supports it. A mechanical blade still turns a physical lock unless that lock is changed or rekeyed. On a Mercedes that blade is the emergency key element inside the missing key.
Mercedes Key Fob Faults and Their Route
Mercedes key fob faults are handled under the car key fob repair service. Whether the remote is repaired or takes another route is confirmed after the fault is identified.
A Mercedes key that locks and unlocks the doors while the engine stays off is a different fault, on the immobiliser side of the key, and it is identified at the car.
Mercedes Van Keys and the Van Service
Mercedes sells the Sprinter and the Vito as its van ranges in the United Kingdom, with electric versions of each. Keys for a Mercedes van are covered under replacement van keys, where the lock points of a van are dealt with, and support for the van is confirmed on the call.
Makes Adjacent to Mercedes With Key Pages
BMW, Audi, Volvo, and Jaguar and Land Rover are adjacent makes to Mercedes, and each has a key page of its own with its own key system names.
A Mercedes Retailer Compared With Inta-Lock
Comparison. A Mercedes retailer and Inta-Lock each supply a key that is matched to one individual vehicle.
Differences. The retailer route runs through the retailer, while Matt travels to the Mercedes and works beside it.
Similarities. Each route asks who is requesting the key and which vehicle it belongs to, because the work is security related.
Effects. Completing supported key work where the Mercedes stands removes the reason to move the vehicle solely for that job.
