Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Perhaps you have a faulty infrared sensor in the headliner above the rearview mirror that is setting the alarm off after everything has been "locked" down.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Have an '04 C4S. Central locking works, but when I lock the car using either the key or the fob (single or double click on the key), the alarm sounds if I don't start the car in around 20 sec or less. Checked the Renntech DIY with no luck. Any suggestions? It's embarrassing to have this happening constantly. Thanks - Phil

POST 2Original post

Assuming that your '04 works the same as an '02, if the car "locks" fine with the fob without blipping the horn at you (meaning something has been left open, like the glove box, boot, armrest, or engine lid), then your alarm should be set and ready. Is the little red light blinking on the dash after arming? After 20 seconds, it alarms, correct? Perhaps you have a faulty infrared sensor in the headliner above the rearview mirror that is setting the alarm off after everything has been "locked" down. Try cleaning the sensor lenses and see if that helps. It's likely not the sensors in the glove box, boot, armrest, doors, or engine lid since you're able to arm the system. IIRC, the infrared sensors are not activated until the car is locked down. Cheers

POST 3Original post

I'm not sure I understand... you say then you say... do you mean unlock the car? why would you start the car after you locked it? usually to reset the key fob (after the week of inactivity), you open the car and then press the key fob. this will reset it.

POST 4 / ORIGINAL POSTEROriginal post

Sorry for the confusion - yes, I meant unlock the car. After around 20 secs, alarm goes off.

This is a source reference. Confirm exact model applicability in the original material.
