Power Windows, Central Locking & Immobiliser Repairs in Mascot
Power windows stuck, central locking playing up, or a key that won’t start the car — we diagnose and repair the fault properly.
Power windows, central locking, remote keys and immobilisers all share components — switches, motors, regulators, wiring looms that flex every time a door opens, and body control modules that tie them all together. A fault in one often looks like a fault in another, which is why proper diagnosis matters before parts are replaced.
Immobiliser faults in particular can be frustrating: a car that won’t start with a genuine key sometimes points to a failing key transponder, sometimes to the immobiliser module or its antenna ring, and sometimes to a flat key battery mimicking a bigger fault. We test each possibility in order rather than replacing the most expensive part first.
What's included
- Power window motor and regulator diagnosis and repair

Door Locks — common questions
My window went down but won’t come back up — is that expensive to fix? +
Often it’s just the window regulator or motor, which is a straightforward repair. We diagnose it properly before quoting rather than assuming the worst.
My car won’t start even with the correct key — what could that be? +
It could be the key’s transponder chip, the key battery, or the immobiliser system itself. We test each in turn to find the actual cause rather than guessing.
Can you cut and program a spare key? +
Yes, for most makes and models we can cut and program spare or replacement keys, including transponder programming for immobiliser-equipped vehicles.
