Alarm resetting recharged battery after going flat,when putting battery back on alarm wont go off

put key in ign switch turn it on

Battery went dead or replaced, it set the alarm. Some alarms can be reset with the key, some with a scanner, some at the dealer. Year, make , and model would be helpful.

Not familiar with your car, but, modern cars with computers don't take kindly to removing the battery. You should ALWAYS put a temporary battery across the posts to maintain the computer settings.
I suspect you'll have to go back to an agent to rectify this.

When the alarm sounds, turn the key to the RUN (NOT START) position, then OFF - do this 10 times rapidly.
Many alarms will turn off and allow the car to start with this method.

Put key in drivers door lock and turn counter clockwise. must recharge battery or alarm will keep tripping.

Theres a keyhole on the back of the siren in the engine bay, if the key is in your possession you can turn off the alarm with this - Hopefully* Also the control boxes for the alarm/immobiliser are usually under the front seats, there are 3 boxes throughout the car and they can be hard to find, each has a fuse - check the fuses and replace any that are blown - plugging and replugging the fuses may reset the immobiliser anyway I can't find a manual for it but i'm looking - try this out first and tell me what happens - there IS a proper reset procedure - but it's not exactly broadcast. i'll do my best to track down the manual for the pa1000, but it is an obsolete system and will be hard to find.

Only Recharge the Battery with both the Cables: Positive and Negative removed from the Battery.
With the Charger OFF the Battery - Reset your Alarm turning it OFF.
Then Disconnect the Battery completely.
Never Recharge a Battery while it is still connected.

take +and_ cabels off now turn on key now put cablels back leave key on the whole time untell done

hook up battery and press alarm button on the key fob or just insert key and start truck alarm should shut of on its own

You should have a switch under the dash and then just turn it to the off position. If you don't or it doesn't work (like mine) then, there is 2 fuses under the dash, put the key in the ignition and turn it forward, pull one of the fuses out and then start the car that should reset it. Then you should be able to put the fuse back. Sometimes if you put the fuse back before starting it the alarm will just continue to try and reset itself, but not start the car. If that doesn't work I have a mechanic who can pull the whole alarm out and when hes done it would look like nothing has ever been installed. Hes very good. I ended having him take my alarm out when I had the same incident happen after the 2nd time.
