Alarm problem

[Kev901]

Hope you can help I had an alternator fitted yesterday 4 hours later the alarm won't stop activating and when I use the key to lock the car the horn beeps twice no lock Nd the bonnet is stuck. It's a 911 1999 model so mot a mechanical mechanism. Any help on why the alarm is going off and. Fix along with how to get the bonnet open as the battery is almost dead. Thanks

Doesn't your car have the red emergency hot "lead" in the bottom of the fuse box?  Pull it out to connect the positive cable of your 12v power source and use the door striker loop for the ground.  Don't try to jump start the car from this post.  You will melt things in the wiring harness.  It is just for applying power to open the Bonnet.

 

If you can get the engine cover open charge the battery from there.  Use the bolt that holds the air cleaner housing to the body and the + post in the junction box.  Sometimes when the battery is almost dead the alarm will not reset and other electrical gremlins crop up.

 

For the Bonnet, try having someone press down on the leading edge while you try the release lever.  If that doesn't work you will have to try the emergency release cable.  It lives in the area in front of the right front wheel liner.

 

There is also an emergency release cable for the engine cover in the left rear taillight.  It lives between the taillight housing and the top of the bumper.  I have had luck gently wedging a rubber spatula in the crease to allow me to snake a thin wire hook in to get the cable out.

Thanks really helped got the Bonnet open and after some investigation looks like the reconditioned alternator is draining the battery which has now got a couple of dead cells. Took alternator off and replaced battery with an old one and looks like no charge being lost so looks like this may be the problem.
