Thread: Wont lock and alarm is on continuously

Maybe the inertia switch?

If you are standing in front of the car, looking at the engine, on the right hand side, mounted on the firewall, is a small, black thingo.

Press this down & see if it resets, then try again.

OR, it is unlikely, but possible one of the cables to it have rubbed thru???

Ta, pressed it and it definitely moved down, but, still nothing happened. Press the unlock button the lights flash but the car is already unlocked, press the lock button the Black Thingy gives a strangled beep.
Pressed the BT again but no movement.
I must say the car has been standing in rain all day with some of it going under the open bonnet.
This morning the A/C fan was running, I spilled water over the fuse block last night when filling the radiator bottle.
I think when the rain stops I need to get the air blower out along with the WD or CRC.
Any more ideas I'm willing to try, thanks all.

Going on with the black thingy, if it has been wet will disconnecting it take it out of the system or will that merely ensure it is seen as a fault?

Mike

Battery charge or faulty battery is a possible problem, are you sure you fully charged your battery? The BCU takes some time to be activated once you've hooked up the battery, and if the battery isn't fully charged it won't be reading your fob signal. Try charging again or test with multimeter to rule that out

Thanks, the battery is good, 800CA and now fully charged, engine starts instantly.

The inertia (black thingo) beeps when trying to lock, nothing else happens, horns are disconnected but the alarm sounds the moment I reconnect one.

Apart from not having the horn working am I likely to have further problems if I drive the car?

As I have been working in the engine bay and have de-greased the bay could I have wet something that is causing this problem?

Dunno what I did, either to cause the problem nor to rectify it.

Tonight I decided that as this problem arose after disconnecting the battery I would again disconnect the battery and re-connect in a different sequence, see if that made any difference.

Before doing that I locked the doors with the dash switch, (I had tried that before and knew it would work), and checked that they would unlock properly, they did. So I tried locking them with the remote and they locked.

I re-connected the horns and they did not sound, I will start the car in the morning, say around 0730 just in case the alarm does go off again, figure if I'm up, the rest of the neighborhood should be too.

The only thing I can think of is that whilst I was working under the bonnet something got damp causing something the problem.

Thanks to the guys the tried to help, there is no doubt that I will keep your advice in mind for the furure just in case, it's certainly something I did not know before.
