Central locking stopped working in car?

audio and central locking just stopped working in my suzuki ignis car, can any one help or is it going to be a costly trip to the mecanic? thanks in advance





i have changed fuse and the audio appears to be fixed but once i turn the engine it goes off again, thinking fuse blew ...happened a few times now. with the central locking, havent tried anything yet as it only happened this morning.|||Do you have a phone charger or something similiar plugged into cig lighter? It does suggest a blown fuse as it fixes it until it turn the ignition on. Have seen similiar problems and that has been the cause. Worse case could be BCM (body control module) which could be 2-300 quid. But that's worse case. Haven't seen anything too common come through warranty.|||if you asked the Suzuki dealer nicely "in your experience, have you heard of this happening?" "is it a common problem?" they might tell you what causes it. y'know, polite, friendly, flattering their expertise etc.|||Fuses are designed to blow when there is a fault. No point just changing the fuse without fixing the fault which could be aywhere in the Audio and central locking systems.
