Will not start but turns over


Check if security light is on, if so, must reset. To reset, put key in ignition and turn to on position. Security light will start flashing on and off. Leave key in on position until security light stops flashing and turns off completely. This will take approximately 10 minutes. Then turn key off and take out of ignition. Put key back in and start car. Should now start

Car trys to start but won't Car acks like it wants to start but won't


This problem can be from a problem with the security system. To test this theory on most cars turn the ignition to on and see if the security light continues flashing. If so this may be the problem. Most owners guides will tell you how to reset the system so the car will start. If not, one thing to try is leave the ignition on for a long time (10 minutes or so). When the security light stops flashing the car should start. This problem seems to be from the car ageing and the key not working as when the car was new.

We have used compressed air in the ignition and then put wd40 on the key and run it in and out. This seems to help with the recurring problem but doesn't make it go away.

I don't know the permanant fix. I suspect a new ignition switch which is not a cheap fix.

Changed ignition switch now security light stays on and truck starts and kills


You need to relearn the passlock system (security). There are 2 ways. One is with a scanner, which most diy'er wont own an expensive one to do it this way, here is the manual way. Start the truck and let it run until it dies. The security light should then be flashing. Leave the key in the run position until the security light stops flashing (about 10-15mins). After the light stops flashing turn the key off. Try to start the truck again. It should do the same thing (run for a few seconds and then die with the security light flashing). Again wait for 10-15 mins for the light to stop flashing and then turn the key off and repeat the process one last time. That's a total of 3 times. Once you finish the process the 3rd time. Let the truck sit for a minute with the key off. It should now be programmed and start and run normally.

1996 Oldsmobile Achieva: Security light flashes upon startup


Here is what you do, but only when the SECURITY light flashes - if it is always ON or OFF it's no use.
Turn the key in the ignition to ON.
Wait for exactly 10 minutes ( SECURITY light will flash for 10 minutes and then stay on SOLID)
Turn the key to OFF
Wait 5 seconds.
Turn the key in the ignition to ON.
Wait for exactly 10 minutes.
Turn the key to OFF
Wait 5 seconds.
Turn the key in the ignition to ON.
Wait for exactly 10 minutes.
Turn the ignition OFF.

Start the car normally.
It has relearnt the keycode and you're good to go.
NOTICE - it takes 30 minutes to relearn, that's THREE cycles of ON - 10 minutes - OFF.

Good luck.

No keys


If you want to initiate a new master key.... 1. Insert new key into ignition cylinder and turn it to the ON (RUN) position. The security light on the dash will flash for fifteen minutes.
2. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder OFF and then back to the ON (RUN) position. The security light on the dash will flash for fifteen more minutes.
3. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder to OFF and then back ON (RUN) position. The dash will flash for fifteen more minutes.
4. After the security light stops flashing the third time, the new key has been programmed into the vehicles computer and will operate the car. It has replaced ALL the previous electronic key codes and is the ONLY key programmed into the vehicles computer.

The dealership should be able to do this for you without a current key, of course this means towing the vehicle to them. See if they will sell you a key and you program it yourself.

hope this helps. I found the above info at FordF150.net

Key Does Not Work


It could be that chip inside key just went bad. Do u have a 3rd key? That works? If so take the 2 good keys and turn the igntion to run postion for 3 secs each then do the same for the 3rd key and this will reprogram it if the chip is ok. If you do not have 2 good keys then u will have to have a scan tool that will link up with PATS system and perform security access to reprogram it.

Security light flashing


Take the Original Ignition key out to the car. Get in it and turn the key on. Every light should light up like your going to start it. The factory security light will flash. Leave the ignition on until it stops flashing. Should take about 10-15 min to do it. once it does, shut the key off and then turn it over to start the car.
