Changed battery in my 07 toyota tundra. when I connected the new battery, the alarm goes off. cannot get vehicle to crank or turn offthe alarm


You have upset the anti-theft system.

Disconnect the battery. Put a household bulb across the battery terminals for 3 minutes. Hold the battery leads together for 3 minutes. Leave the battery off for 1 hour. Put your key in the ignition, but not on. Connect the negative lead of the battery. Connect the positive lead in one go, bang and on. Leave the car for 15minutes to reset. Start the car normally.

Number 1 tip from a mechanic friend of mine. Maintain the power to the vehicle when changing batteries by using 2 lengths of wire or jump leads.

Antitheft alarm on our 2001 mercury sable goes off on its own


Get a new car! JK - my 2002 Sable does the same thing. It can be 5 times a day then not for a month, or 2-3 times a day for a week straight. It happens in different locations and different weather and different times of the day. To my knowledge has never done it in my garage at home.
I have not called a dealer. Has anybody ever found the real problem? Could it be in the remote itself? I tried leaving it unlocked at work, but yesterday it went off just as I was reaching toward the door handle.

Hi Michael, we have a MOD600 in our home also & need to reset the whole system - did you end up finding anything useful?

On Simon panels, the master code should default to 1234 if it's been powered down for several hours (I can't remember how long, at least four hours, possibly 12-16). So, unplug it from the wall and disconnect the system battery and leave it for the night. Power it up by plugging in the battery first and plug it into the wall. Then enter the code as 1234. It should annouce that the alarm system is disarmed. If so, your code is 1234. ;)

When removing the battery, be very careful to not break the little tab that holds it shut! Can't stress that enough.
