I need to program the alarm to double pulse to unlock for toyota tacoma but i dont have the manual. it only unlock the drivers door. i need everyone to open. thank you. the alarm is the old one not the new.

Try putting the key in the driver door lock and turning from lock to unlock. That should dissable the factory alarm system. You may have to do it a few times before it works.

You need to use the main regular key. Not keyless remote... LOCK THE VECHELE DRIVER DOOR WITH KEY, THEN UNLOCK DRIVER DOOR WITH KEY. Once you have done this place key in ignition try to start car, and security problem should be resolved.

The Camry you purchased may not be equipped with a power trunk. Press and hold the trunk button for appoximately 4 seconds. The trunk should release if the wire is connected and, you have a power trunk.
The Camry (and other toyotas) require a double pulse on the unlock wire. If the double pulse is not programmed the aftermarket unit will mimic the factory keyless entry. One press of the unlock button opens the drivers door. Immediately press the unlock button again to unlock the other doors.

The problem isnt with the alarm, it is probably with the tech that installed it. If the doors all unlock after pressing the unlock but many times in a row then that means that the tech has to program double pulse unlock in the features menu. If it still only unlocks one door then he must have gone to the wrong wire for the doorlocks.

RED opens the drivers door, BLACK opens all the doors, and GREEN turns on the head lights

no.. u need to have a dealer do it.. they also have a tool ti check it the remote is transmitting a signal as well

If after unlocking the driver door with the key and still no luck, put the key in the ignition and turn forward to start (if it won't start turn forward anyway) then push you're red reset button on the dash. That should do it.

turn drivers side 2 times to right should unlock hole truck

The first programming option allows you to set the entry unlock to: (A) unlock the driver door with one push, and the remaining doors with a second push OR (B) unlock all of the doors with a single push.
