If you drive a Mercedes with Keyless-Go in Erdington, your car can be unlocked and started by thieves who never touch your key. LockCar fits hidden relay immobilisers for Mercedes owners across B23 and B24 – from the terraces around Erdington High Street to the family homes near Pype Hayes Park – with a mobile engineer who comes to your driveway or workplace.
Why Mercedes owners in Erdington are adding an immobiliser
Many Mercedes models use Keyless-Go, which unlocks and starts the car when the key is close by. Like other keyless systems it judges ‘close by’ from a radio signal, and that signal can be relayed from inside your home. The factory immobiliser also trusts the car’s own electronics, so methods such as OBD key programming can register a new key without the original.
Erdington’s position next to Spaghetti Junction (M6 Junction 6) and along the A38 Tyburn Road means a stolen car can join the motorway network within minutes. Many Mercedes here are parked on driveways or the kerb directly in front of the house, which keeps the key and car within relay range if keys are left near the door.
How keyless Mercedes theft works – and how an immobiliser stops it
A relay attack uses two devices: one near your front door picks up your Mercedes key’s signal, the other beside the car replays it, and the car unlocks and starts as if you were standing next to it. A LockCar immobiliser adds a hidden relay in a circuit the engine needs. It only closes when your separate LockCar tag or app is present – something a relay device cannot copy.
Many Mercedes keys can be put into a standby mode that switches off the keyless function until the next button press – your owner’s manual explains how for your model. Use it at home alongside a Faraday box.
Parking and security tips for Erdington
Use your Mercedes key’s standby mode at night if your model has it, keep keys in a Faraday box away from the front door, and fit a hidden immobiliser so the car stays protected when you are out – at work, at the shops or at the station.
If your vehicle is ever stolen, report it to West Midlands Police on 101 (or 999 if the theft is in progress). Our guide on what to do if your car is stolen walks you through every step, and our car theft prevention guide explains each theft method in more detail.

Mercedes immobiliser Erdington: questions and answers
Do you cover Gravelly Hill, Tyburn and Pype Hayes?
Yes – all B23 and B24 neighbourhoods, plus Castle Bromwich (B36) and Sutton Coldfield (B72–B76).
I also have a BMW – can you fit both in one visit?
Yes. See our BMW immobiliser Erdington page, and mention both vehicles when you book.
Is LockCar compatible with Mercedes electrics?
Yes. We fit to Mercedes 12V systems across the range, including C-Class, E-Class, A-Class and SUVs such as the GLC and GLE, and install so that factory functions keep working as normal.
Why isn’t the Mercedes factory immobiliser enough?
The factory system checks for a valid key, but a relay attack makes the car believe the key is present, and OBD programming can add a new key. A LockCar immobiliser is independent of both: it needs its own tag or app before the engine can run.
