    Thank you.



    It can be a problem if the key is worn. But only is the key is able to remove in RUN or ACC position.



    OK.. The KEY on your car, has NO CHIP.

    The CHIP is part of the Ignition lock Cylinder.

    The CHIP. Is on the Fix part of the cylinder.

    In the part moved with the KEY is there a Magnet that send Magnetic siganl to the chip....

    This is the basically axplication of how work the chip on your car.



    Thank you.

The remote does not start car. Also the marker lights stay on even when the key is off.


Remove the remote system. I haven't put one in, But have taken out several hundred. Good ones last 5 to 7 years. Cheap ones will last maybe 2 years. Once they start dieing, they will eventually keep the vehicle from starting.

Anti thief light not blinking. Car wont start. key fob red light will flash but car wont turn on


If it doesn't start with the key either. Remove the aftermarket alarm/remote start system. Some thing you might check first is the neutral safety switch. On the transmission close to the shifter cable. Any way. after market alarms don't last that long. Even the best on the market seem to only last about 6 to 7 years. Cheap ones are lucky to last up to 2 years. Once the start going out, they can cause all sorts of different problem.

When I start my car with the remote, the doors don't stay locked. Any ideas?


High dollar aftermarket remote start systems last about 5 years. Cheaper ones, lucky to get 2 years. They cause all kinds of problem when they get older, your's is one. Others are no start, doors lock and unlock by them selves, Car starts by itself..Tear it out. One wire at a time. Repair any wires that were cut as you go. If you don't. Someday soon your car won't even start with the key. Security..

I have a 1999 Toyota Corolla and electronic key system has only locking button. The unlocking button is lost and I was told I need to buy one online. Last night after coming home I have locked with...


I am having the SAME problem with my 99 Corolla, Still searching for a way to disable the factory security system, for the last two years I have the vehicle hotwired through the headlights to start it. (1 wire to battery positive, 1 wire to starter hot lead, touch them together.) unfortunately this has proven very dangerous as the vehicle will start even in gear, and take off without a driver. additionally, because the alarm is going off continuously, the battery dies if not disconnected after every use. I found the fuse in the relay box that disbles the alarm, and the car starts fine, unfortunately, It it also the fuse for the alternator, so that solution will not work either. If anyone has found true way to disable the system, PLEASE offer your suggestions!

1996 Olds Achieva: Security light flashes upon startup


Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.
