Selly Oak sits on the A38 Bristol Road between Birmingham city centre and Northfield, right next to the University of Birmingham and the Queen Elizabeth Hospital. That mix creates a very particular parking picture: terraced streets in Bournbrook where cars sit on the road overnight, family homes with driveways in Selly Park and Weoley Castle, and hospital and university staff who leave their cars for long shifts. For BMW owners, each of those situations carries a different risk – and a hidden LockCar immobiliser covers all of them.
Why BMW owners in Selly Oak are adding an immobiliser
Many BMWs built in the last decade have Comfort Access – the keyless system that unlocks the car when you touch the handle with the key in your pocket. It is convenient, but the car decides whether the key is nearby purely from a radio signal, and that signal can be relayed. BMW’s factory immobiliser also trusts the car’s own electronics, which is why newer theft methods such as CAN injection and OBD key programming can get past it without the original key.
In Selly Oak’s older terraced streets, the front door often opens straight onto the pavement with the car parked a few metres away. That short distance is exactly what relay devices rely on – a key left on a hook inside the front door can be within reach of a device held at the letterbox. The A38, the A4040 and the Selly Oak New Road make it easy for a stolen car to leave the area quickly, so preventing the car from starting at all matters more than recovering it later.
How keyless BMW theft works – and how an immobiliser stops it
In a relay attack, one device near your front door picks up the signal from your BMW key inside the house and passes it to a second device beside the car. The car believes the key is present, unlocks and allows the engine to start. With CAN injection, thieves reach the car’s data network from outside – often behind a headlight or bumper – and send fake “key is valid” messages. OBD key programming uses the diagnostic port under the dashboard to register a new key. All three methods defeat the factory system; none of them can close a hidden relay that is controlled by a separate LockCar tag or app.
Check your owner’s manual or ask a BMW dealer whether keyless entry can be switched off or limited on your model. Combined with a Faraday box at home and a hidden immobiliser, it removes the easiest route in.
Parking and security tips for Selly Oak
If your front door opens onto the street, keep your BMW keys in a Faraday box at the back of the house rather than in the hallway. If you work shifts at the QE or on campus, remember that a Faraday pouch only protects the key while it is inside the pouch – a hidden immobiliser protects the car for the whole 12 hours it is parked. On shared driveways and student streets, a dashcam-equipped unit also gives you evidence of damage or tampering.
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.

BMW immobiliser Selly Oak: questions and answers
Can you fit my BMW at the QE Hospital or University of Birmingham car park?
We can fit wherever it is safe and permitted to work. Hospital and university car parks may need permission from the site, so many staff prefer a home or weekend appointment. Tell us where you park and we will suggest the easiest option.
Do you also cover Bournville, Harborne and Northfield?
Yes. Our Selly Oak engineer covers all of B29 plus neighbouring Bournville (B30), Harborne (B17), Northfield (B31) and Edgbaston (B15).
Will an aftermarket immobiliser affect my BMW warranty or cause fault codes?
A LockCar immobiliser is fitted without altering the car’s software or original key system, and is installed so it does not trigger dashboard warnings. Keep your fitting invoice with the service history. If your BMW is under manufacturer warranty and you want extra reassurance, ask your dealer before booking.
Why isn’t the BMW factory immobiliser enough?
The factory immobiliser checks that a valid key is present, but it relies on radio signals and the car’s internal network. Relay attacks fake the key’s presence, and CAN injection or OBD programming work through the car’s electronics. A LockCar immobiliser is a separate hidden relay that needs its own tag or app, so those methods alone cannot start the engine.
