interesting issue today, my key would not unlock the car.  Lock button worked but nothing from the unlock button. I opened the car with the key in the door lock and, of course, the alarm went off.  With only a lock button to use, I stopped the alarm by locking the car. One issue with that was that set off the motion detection with me in the car so more siren!

I managed to get home by locking the car, pressing 3 times lock to disable the motion detection.  Once home my other key unlocked the car successfully, although I did go through the siren pantomime getting out of the car on the driveway. 

I will try to work out what is wrong with the key at the weekend.  In the meantime I have a question:

Which fuse would remove power to the alarm?  And without power does it die or is there a battery backup?

Hi. Tbh mate, the question of disabling alarms is a very touchy subject and not really for open forum discussion as you will understand. Iv been here before with a different car at least and it involved linking out parts of the ecu. I'm not saying this is true in this case but I was lucky in that a member pm,d me to tell me what to do. The case is also true when " iv locked my keys in" questions pop up and some bright spark tells the world how to break in safely. Take it to a garage. Good luck.

Unplug the siren in the frunk.
First they came for the socialists, and I did not speak out—because I was not a socialist.
Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me.

Turned out to be a fault with the buttons on the key fob, so that can be another job on the "to-do" list.  In the meantime I will use the other key.

Taking into account the replies, can the MODS lock this as I now do not need to know the answer!!
