Hi everyone,

I'm a happy new owner of an automatic-gearbox, limited version of the Crossfire Coupe. went from a 75cv to this engine... needless to say I am amazed.

I'm having a bit of a trouble with this car however ; the Key fob buttons don't work, as well as the AntiTheft alarm.

Situation is not so great because the trunk cannot be locked without the fob buttons...

To sum up what I witnessed and what I tried :

- the key do emit red lights when clicking on both buttons. changed batteries, realigned the contacts FYI.
- it emits 433MHz signals for both lock / unlock actions (accurate frequency for EU)
- the car turn signals don't flash
- same thing on the instrument clusters
- tried reset the key fob using , but noticed no change after that
- no chirp detected when clicking the fob buttons while out of the vehicle
- centralized locking fully works when clicking on the console

some more context :

- brought back the car on thursday, changed the car battery because it had died some months ago and needed a booster to start the engine
- antitheft alarm doesn't work, the actions on the console button give no response
- the fuse box has been reviewed, no trouble with the related fuses (16 - 23 I think)

According to RedDog comment on this thread, it seems that the Alarm battery may have died.

2 questions :
- I didn't find any relevant alarm module on ebay, since the links provided are 5+ years old. What should I look for?
- Index of Crossfire problems do describe a way to open the alarm module and fix the battery issue.

Is there something else I forgot to check for? Do you have any workaround for locking the trunk in a quick way?

Thanks for your help!!
