Car alarm won't disactivate

It sounds like there may be an issue with the factory car alarm system on your 1996 Toyota Camry that is preventing the car from starting. If the alarm system is preventing the starter from getting power, it is likely that the alarm system will need to be repaired or replaced in order for the car to start.
If the Toyota dealership does not have the parts or knowledge to repair the old alarm system, it may be difficult to find someone who can fix it. One option you could try is contacting a specialist who works on older car alarms and see if they have any experience with the alarm system in your Toyota Camry. Another option is to try finding a used factory car alarm from a wrecker or online that is compatible with your car and installing it to see if that resolves the issue.
If you are unable to repair or replace the factory car alarm, you may need to consider installing a new aftermarket car alarm system. An aftermarket car alarm can be purchased from an automotive parts store or online, and a mechanic or an experienced car enthusiast should be able to install it for you.

Here is the reset procedure:
1. Have the Valet Button in the OUT position. ( It is located on the dash panel left of the steering column)
2. Connect the battery - the alarm will sound.
3. Put the key in the ignition and turn to the ON position,
4. Push the Valet Button to the IN position.
The alarm will be reset, and the Valet Button will glow red.

Move the Valet Button to the OUT position again.
Repeat steps 3 & 4 and the Valet Button will become unlighted.
The car will start and everything will be fine.

Put the key if the door lock and unlock it and see if that unarms it

Just unlocking the car with the key turns the alarm off.

that means you have an aftermarket alarm previously installed have it remove from the car or try to find the swtch under the dash to unarm the alarm manually
all you have to do is locate the swtch and whit the ignition on turn the swicch ones and that's it the switch must to be small some where under the dash but if you can't find it just have some autorepair remove your ald alarm system
