Default 1999 Toyota Camry Anti Theft System

I have a 1999 Toyota Camry LE. When I bought it, I was told that the Anti Theft System did not work; and until today, I had never heard nor seen any indications that the system was engaged. BUT, today we took the ground cable off the battery as the car would not start and when we did, the alarm went off. The little red light to the left of the steering column flashed, the horn blew, the emergency flashers went off. It didnt matter whether I was in the car, out of the car, door open, door closed. After 30 seconds it would stop.

This lasted as long as we had the cable off the battery. - I have read tonight that this is part of the system. This is my problem I received a key fob with car but never really used it as the key was "wiggly" and I was afraid it would break off. I got a key made at Lowe's and have been using that for three years. At this point I cant start the car even after getting another battery. How do I deactivate this alarm system without spending mega bucks at a dealership ??

By reconnecting the battery you may have triggered the alarm system.

You alarm my have immobilized the engine. If this is a Toyota installed alarm try locking the car and opening it with a key.

If you have the type of key with the chip inside try starting it with this key, try both gray and black key if you have them.

If you have some kind of aftermarket alarm try the following: Look under the dash for a button or switch. If there is one try the following: Turn ign key on to the position before engine crank. Within 5 seconds press and hold in the override button until the LED (the blinking light) in your dash area goes solid and the siren chirps once.

If there is a toggle switch instead of button repeat the process but turn the switch in opposite direction then turn ignition switch off.

Many after market alarms are installed into the ignition switch Remove the cover under the steering column and look at the wiring to the ign switch area to see if something was added.

Removing the fuses this alarm should disable the system. If the alarm was wired in the typical way the starter kill circuit is wired in a normally closed configuration and the car should start.

If alarm was wired in a normally open method find the starter wire (red wire in the 98 Camry) and reconnect it to the ignition switch wiring.

If the car has a remote try the site below to determine the vendor and thus be able to contact them for instructions.


Next time you change the battery if possbile keep power to the battery terminals via a small secondary wire.

We found the owner's manual and found a diagram of the fuses under the hood. The alarm fuse is there. We took it out and everything was fine except for the fact that we then had no horn at all. So, after driving the car for about 20 mins, we put the fuse back in and everything is now back to normal.

Thanks for the reply.

hey, i don't know if this has been mentioned elsewhere, but... with the keys in the "ON" position, push down on the red flashing button on your left hand side, underneath the dash board for about 5 seconds. and then start it. it took my dad and me AGES to figure out how to stop it.
