Your alarm will have a manual disarm somewhere. If you have a small cylindrical device with your keyfob, there will be a receptacle somewhere near the drivers seat. You need to open the door and press the two items together. If not, you may have a button hidden somewhere around the place. In this case the procedure is usually to hold the button while you insert the ignition key and turn it to the ON position.

Some alarms have a small round key. If your alarm has one, or if your keys came with one and you didn't know what it was for, you can open the bonnet, pop a little cover on the alarm box (it will be bolted to the firewall, usually on the right hand side as you look at it) and turn it off until you can get it repaired, or get a new one fitted.

If none of this works and your alarm is an alarm only and not an immobiliser, you can simply open the bonnet and cut all the wires going into the alarm. If it is also an immobiliser, don't touch anything unless you're handy with a soldering iron and multimeter and have a few hours spare. (You would need to pull the cover down from under the steering wheel, then start taking electrical tape off the big block connector with thick wires, and then start rebuilding the wiring that's been chopped to make way for the immobiliser system on a colour-matching basis.)

Check the next Wiring Diagram for other details and the Lock Wire Diagram.

Hope helps.

    Many thanks for your comprehensive solution.Unfortunatly i dont have the turn off key for the alarm,and the car started with the wires half in/out.but when i put them in fully it turned off straight away,im begining to think that the alarm is part of the immobilizer! But i will follow your comments to the letter,ive printed them off so ive got them to hand!, and i will let you know tomorrow what happens.Regards,Paul.

The alarm is faulty on my 1990 celica,it is broken and is stopping the car from sparking!any bodge etc?i have an account but fixya wont recognise my password again!!!

Sorry about your celica, I do realize these cars are **** but none the less they are fixable. Disconnect the battery and wait 30 sec. Reconnect then turn the ignition to the on position allow the alarm 2 hrs to reconfigure itself and then start the engine. Sequence is now complete.

Anyone any ideas for my toyota celica 2.0 gt have

Hello, and welcome to FixYa. Please allow us to assist you.

Sounds to us like you may have a timing belt that has jumped a tooth or two. Here is a good way to check to see if this is indeed the case.

Crank the engine until the timing mark on the crankshaft pulley is at TDC, the zero mark. Next, remove the distributor cap, and note where the rotor is pointing. It should be directly under the tower for the number one cylinder. If it is not directly under #1, the belt has jumped time, and a new belt will be required.

Thanks for choosing FixYa today.
