Either you may be using a key that you had copied from the original or your chip went bad in your original key. Most of cars now a days have the key censor in the key so if it is the incorrect key it will not start your car or if it does not read that chip it will not start

SOURCE: theft light blinking/car won!t start

If you have key numbers on the door, you should enter the code, then immediately start the truck. If this does not work contact the dealer for a sequence to reset the alarm.

Theft light blinks rapidly. can't start engine. 2002 merecury sable gs


Reset the alarm system. It won't start unless you do. If you can't reset thru your system controls, disconnect the battery ground terminal for 24 hours the re-connect. This will reset the computer and alarm should be cancelled.

On a 2004 Buick rendezvous there is a little red light that keeps blinking expect when the car is running. I'm pretty sure its draining my battery. Any suggestions?


That little red light is your anti-theft system and it does not drain enough power to drain your battery unless your car is sitting for a year. I would check for a draw. Unhook your negative battery cable and hook a test light between the cable and the negative terminal. If the light lights up brightly, then you have something draining the battery at a significant rate. I start by unhooking the main cable off of the alternator, this is a prime place to start for a battery drain. If unhooking the alternator does not dim the test light then move on to the power distribution center and pull fuses and relays one at a time until the light dims, this will at least narrow down the circuit that needs attention.

Anti theft won't reset. Battery won't charge. Tries to start on it's own.


The system may be activating because there is not enough power in the battery?
Check the batter connections and power cables.
Are the posts clean and tight.
Are the cables going to the battery, alternator and starter in good condition. Check to see if the insulation on the cables have not worn away some ware along the cables and shorting out.

Some anti-theft systems need to be reset after the battery has died and/or been replaced. Check your driver's handbook for more information on this.

You should have disconnected the battery and fully charged it before starting the car.
The low voltage may have damaged some of the electronic components in the alarm system.
Charge the battery fully, then reconnect it and see if that helps.

This is ONLY a suggestion. Take your positive battery cable off for at least ONE MINUTE. Then put it back on. Other than that I wouldn't know. The car has a computer. Sometimes resetting them gets rid of small quirks. If the car didn't turn over at all you might need a new car battery. But try the battery cable thing first. Its the least expensive.

92 olds 88 royale, 3800, wont start after hot, dead key no sound, sometimes starts with a jump, security light not blinking.


Lots of possibilities.
If the alternator was not putting out 14 volts or more when reved up, then the battery could be draining as you drive.
But then you would still get a click from the soleniod, and jumping would work.

My best guess would be dirty battery terminals, since they can rapidly change with chemical reactions. They should be taken off, brushed shiny and greased.

But starters can fail from heat.
Another possibility is a safety switch could be bad, like neutral safety or clutch safety switch. Try neutral instead of park.
And the anti-theft system is also possible.

No power to anything - how do I reset anti-theft system? Checked battery at Wal-mart - print out says okay low on charge. Charged battery for several hours on slow charge and then fast charge. Battery...


no... no power to anything means like the headlights are inop and such

in that case its a battery or battery cable issue

assuming you have headlights and power to accessories and the vehicle still will not start AND the theft light is flashing then YES your anti-theft system is trying to keep the car from what it thinks is a theft issue

simply pressing the unlock button on your remotes will resolve this

assuming you do not have the remotes then you will need the anti-theft computers reprogrammed at a dealer or good garage

keep us posted
