Anti theft system bypass

Ever since I bought the car it has had a periodic issue of not starting... not the battery, not the tranny, not out of gas, it has been said it may be an anti theft issue... I have to get out of car, lock all doors, wait 10-15 minutes, then reopen car using key (not clicker) and try to start again. Usually it will start then. This problem has happened a couple times a year and gone as long as 18 months without issue. however it has done it now 3 times in 6 weeks. WHAT CAN I DO? Toyota has had it in their local shop and the mechanic will turn it over 100 times and not get it to repeat the issue.

SOURCE: 96 Toyota corolla. I turn the key, all electrical,

you need a starter. I'm 99% sure. Remember were just guessing here from what you tell us. As a technican I would have to test some stuff to be sure but most likely its the starter.

SOURCE: Starting problem

Hello LostLynne.
The most common issue is a bad contact in the starter solenoid.
This solenoid is part of the starter assembly and makes the high amperage battery to starter connection
When you hear the click the solenoid is activating but not completing the battery to starter contact.
If this is an original starter or been on for a long time I would suggest changing the starter assembly.
Also in your under hood fuse/relay panel there is a smaller relay that activates the starter solenoid that should be checked before replacing the starter. Although less common for that to happen it does occasionally cause a problem. Easy to replace too.
If you have further questions please ask me.

I will assume you have a factory Anti-Theft system. Here is the rest procedure unlock the system which was triggered by the battery change and resultant loss of power. Do the reset exactly as written.

Put the key in the ignition, and turn forward
all the way just before cranking position. Then within
5 seconds, locate, press and hold in the
valet/overide button, found under the
dash area, (push button, spring loaded)
until the installed LED (the blinking light)
in your dash area goes on solid,
and the siren chirps once.

(Your valet switch might be the toggle
(on/off) type. in this case, key on,
flip switch in opposite direction,
then turn the key off.)

This should reset the alarm, and reset
the grounded relay on the starter wire,
allowing you to start the engine.

SOURCE: I have 2001 toyota corrolla,

underneath the driver side dash you will find that main alarm unit, usually you can disconnect the wires from this and you will have no problems until you can get a replacement FOB for it.

1997 Chevy Cavalier. How do I bypass the anti-theft system forever?

Question edited for clarity and correct name of vehicle.

You can't bypass it Cherie, it involves transponder chips, receivers and the engine computer (ECM).. The anti-theft system is there to stop theft of the vehicle, basically what you are trying to do. You have to fix the system, not find a way around it. This is the reset. As long as you battery is good and fully charged, it should only need doing once.

Just leave the key in the run position and the "Theft System " light on the dash will be flashing. Leave the key on for about 10 minutes and the light will stop flashing and go on solid. Then the theft system is disable.

that is illogical. the issue has to be with the gas tank repair.

So you want to make you car less secure ? .....have the system checked by a RR dealership and corrected. There is no simple way to by-pass the anti theft and a continuing fault may drain the battery over night.

99 ranger won't crank, periodically, has anti theft.

I looked at your security system, it is starter motor disable and fuel injectors. You can usually get the starter crank, but, if it is the security system, it still won't start because of fuel injectors. I don't know any way to bypass security system. You can check for applicable trouble codes, if there are any?

No start cranks but does not fire has spark. has fuel if bypassed by relay fuses good new fuel pump a year ago has fuel replaced battery froze, has prostart remote start, been in 8 years no issues 2000...

check to see if the security light or anti theft light flashes. if that is the case, sounds like the bypass for the remote starter may be causeing the no start by tripping the anti theft system. Remove remote starter and bypass system and join any cut wires back together that may be cut for remote starter. Try starting, if theft light still flashes leave key in the on position after attempted start for 15 minutes till theft light goes solid, turn off and try again. Repeat process for three times to re-learn factory theft system in vehicle. If problem still persists, then take to your local dealer to reprogram factory theft module in the cluster.
