It is a fault with the alarm system, or with the alarm remote. check the battery in the remote (key). If remote is ok, you will have to disconnect alarm to start your car normally. Go to a car electrician , or to a car alarm dealer, or to Ford if the alarm is the original one to fix it or replace the alarm.

Car won't start security light blinks

If the security light is blinking, then the security system is DEFINATELY the reason why your car won't start. The actual cause of the problem is MOST LIKELY a defective ignition switch that is not sending the information from your key to the computer.

Try this:

FIRST try a different key if you have more than one for the vehicle. I have had cars towed into my shop simply because someone was trying to use a cheap duplicate key that was cut at the hardware store. These keys are fine for the doors and trunk. They are great to have around in case you lock your keys in your car. However, they do not have the electronics built into them to allow for engine starting.

If you are using the correct key and a second key also does not work. then...
1. set your parking brake (this will disable your daytime running lamps and conserve battery power.)
2. Connect a battery charger to the vehicle battery if you have one, or see if someone can connect to your battery with jumper cables.
3. Turn the ignition to the START position for about one second. Then release the key to the RUN position. DO NOT turn the ignition OFF.
4. Wait about 10 minutes until the security light quits flashing. Turn the key (without turning it off) to the START position again. The engine should start. If it does not, then you will have to get your car towed in for service.

HINT: you may want to try this a couple times to make sure you are doing it correctly before towing.

If it does start, it is recommended that you have your security system checked for fault codes. I have seen this many times, and it only gets worse and does it more often until this method no longer works to get it started.

Sometimes won't start due to security system .

Are you sure it's security related? Could be starter overheating problem.

I have a 2002 cadillac deville, the service

i'm having the same issue. Dealer said the battery won't hold it's voltage; swapped in a new one. But also said that's independent of the "service security system" fault; which they say might be the ignition module. Were you able to fix your problem?

2002 saturn sl2 will not start for no apparant reason then 1 to 3 days later starts, while trying it 2-3 times a day. Towed to a garage both times and they could find nothing wrong.

Why couldn't they find anything wrong? The main componants should be tested first. (the starter,srarter relay,any related wiring, ignition switch, and all connections at battery, relay, fuse, starter, and eng. block). Good luck.
