Mercedes Immobiliser Sheldon protection starts with understanding the local picture. Sheldon is a suburban area of east Birmingham, located near Birmingham Airport and the NEC. The B26 postcode area covers Sheldon town centre, Lyndon, and surrounding neighbourhoods. With excellent transport links including proximity to the A45 (Coventry Road), M42 motorway (junction 6), and Birmingham Airport, Sheldon is accessible to organised theft rings operating across the West Midlands. LockCar brings professional Mercedes-specific immobiliser installation to Sheldon via a fully mobile fitting service, so your car never has to leave your driveway.
Mercedes theft in Sheldon: why B26 owners are targeted
Sheldon sits between the A45 Coventry Road and the M42 at junction 6. That road network is exactly what makes a stolen Mercedes easy to move. Within minutes of a theft on a Sheldon residential street, a car can be on the M42 heading north or south, or on the A45 towards the M6. Birmingham Airport is nearby too, which historically has made the wider east Birmingham corridor attractive to organised vehicle crime.
Mercedes models are consistently among the most targeted premium cars in the West Midlands. Keyless entry, standard on most modern Mercedes, is the weak point. A relay attack needs no broken glass, no alarm trigger, and often takes under a minute. For Sheldon owners, the practical question is not whether the risk exists, but which layer of protection closes it fastest.
How relay attacks target Mercedes – and how an immobiliser stops them
A relay attack works by capturing the signal from your key fob inside the house and amplifying it to the car. The Mercedes computer believes the genuine key is present, unlocks the doors, and allows the engine to start. Nothing on the car is damaged. The factory alarm usually stays silent because the car thinks it is being opened normally.
A Mercedes Immobiliser Sheldon installation from LockCar breaks that chain at the start circuit. A physical relay is placed in the circuit that powers the engine start. Unless the relay is closed by the authenticated app or proximity tag, the engine cannot start – even if the doors have been opened and the car’s own computer has been fooled. That is the difference between detection and prevention. A tracker tells you the car has gone. An immobiliser stops it going.
The installation process, step by step
Fitting a Mercedes immobiliser in Sheldon is a mobile job. Our approved installer comes to your home or workplace in B26, completes the assessment and fitting on site, and hands the car back to you the same visit. No garage drop-off, no waiting days for the car to be returned.
The process has four clear stages:
What is included in the price: the immobiliser unit, the wiring and relay, the proximity tag or app pairing, and the mobile installation at your Sheldon address. Prices start from £150 fully fitted. There is no hidden charge for coming to B26, and no mandatory monthly subscription on the core immobiliser unit. Dashcam and GPS options are quoted separately if you choose to add them.

Mercedes Immobiliser Sheldon: questions and answers
Will an immobiliser affect my Mercedes warranty? Professionally fitted immobilisers that do not permanently modify the vehicle wiring generally do not affect warranties. LockCar units are installed using approved methods and can be removed without trace if needed. Always check the specific warranty terms with your Mercedes dealer if you are unsure.
Can the system be removed and moved to another car? Yes. LockCar immobilisers can be professionally removed and reinstalled in another vehicle. Contact us for transfer pricing if you change your Mercedes or add a second car to the household.
Does it work on keyless Mercedes models? Yes – keyless models are exactly what the relay immobiliser is designed for. The relay attack targets the keyless start system, and the LockCar relay breaks the start circuit behind it, so the car cannot be driven away even if the doors are opened.
How long does fitting take in Sheldon? A standard Mercedes immobiliser installation in Sheldon usually takes around 60 to 90 minutes. The installer will confirm the estimate for your specific model when they arrive at your B26 address.
