Calling on the wisdom of the forum to help me out here!
Made the rookie error of leaving the lights on and with a dead battery I jump started it with jump leads running to another car (after trying and failing with one of those battery starter packs with the leads on them). Car started fine, ran it for a while, drove about and the battery is now fine. However, the alarm remote won't lock/ unlock the car. I have to do it manually with the key, upon unlocking the alarm sounds, key in ignition, full turn and it stops. I've replaced the battery in the remote- same result.
Anyone know what it could be? I'm pretty sure I noticed it the first time I tried opening the car after jump starting that the problem started, and not had the issue previously. Tried what it says in the manual to reset the unlocking code- pumping the key in and out of the ignition 6 times in 10 secs but there are no hazard warning light flashes which apparantly should show when doing this.......
