Hi,

To disconnect the alarm, you have to find the box under the passenger footwell. Remove carpeting and look for a box with two connectors 12 pins per connector I believe. It will be right under where the front passenger's feet usually rest.

Undo both connectors.

Search the archives about alarm faults. Usually the locking mechanism on the driver's side wears out. You can try switching the passenger-side mechanism with the driver's side.

Good luck,
