Well first off when you change a battery you should use a memory saver so that things will not reset or clear themselves, BUT NOW ON TO THE GOOD NEWS, TO RESET THE ALARM, IF IT IS AN AFTER MARKET OR EVEN INSTALLED AT THE FACTORY ALARM, JUST LOOK UNDER THE DASH ON THE DRIVERSIDE, YOU SHOULD SEE A SMALL BUTTON PLACED IN AN OUT OF THE WAY SPOT, THAT IS THE VALET SWITCH, WITH THE ALARM GOING OFF, PRESS THE BUTTON AND HOLD IT IN, THEN TURN THE KEY, THAT SHOULD RESET THE ALARM BACK SO YOU CAN START IT BEING MOST ALARMS HAVE STARTER DISABLERS, AFTER YOU START IT UP SHUT IT OFF, IF YOU SEE THE LIGHT BLINKING FOR THE ALARM, YOU WILL NEED TO PRESS THE VALET SWITCH AGAIN IT SHOULD SHUT THE LIGHT OFF, IF IT STILL WILL NOT START, THEN YOUR ONLY OPTION IS TO TRACE THE STARTER LINES TILL YOU FIND WHERE THEY SPLICED INTO IT FOR THE ALARM AND DISCONECT IT THERE, THEN INSTALL A NEW STARTER, BUT THAT IS ALWAYS THE LAST RESORT. HOPE THIS HELPS....
i was about to follow the instructions from mechanic0204 I have a 96 toyota 4runner it over heated and shut down and could not restart because of alarm so i went out opened car and bam alarm opened hood disconnected battery was going to try and find misterious button and then follow instructions so i found it sweet real simple a little toggle switch down by your left ankle so i turned it off and started my car fliped it back on and everything works fine ..... so just open your door turn off switch start car and turn it back on lol if that dont work follow mechanic0204's instructions he got me in the right direction.....thanks
Did you mean pressing the button while the alarm is going? or while it is off?

Check the red flashing light it's also a switch
the valet switch I just tackled this problem
the girl who owns the vehicle actually found
the answer in the secure key manual under the owners manual in the glove box this all of course after the service dept at two Toyota dealer ships told me to lock and unlock the doors in a particular order that didn't work but they were profesional and had
good intentions check the l.e.d. ........ Get in
the 4runner unlock all doors put key in ignition turn to on position press flashing red l.e.d. It should turn solid red press it again to return it to it's previous position and start vehicle this is what worked for me hope it helps
SOURCE: alarm goes off when new battery in placed in car,
Hello. If you have a FACTORY alarm system, the deactivte prodedure is to cycle the key off-on (not to start) 5 times, in the ignition. This feature is provided in case you lose the remote, or the remote battery goes dead.
Note: this will only work with the Factory system. If you have an aftermarket system, this answer will no benefit you.
