Question about 2004 Toyota Corolla

1 Answer

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.

Could anti-theft system d mustang cause car to shut off while driving?

Hi, im a retired ford tech, with alot of experience on ford anti theft . Now if you are asking about a built in oem factory anti theft, your not going to be able to bypass it. Now to answer your question, I would say your factory anti theft IS NOT causing your issue. It will make it unable to start,it doesnt kill anything else.

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?

When anti theft light is blinking the car wont start. Can you bypass the anti theft device

On a 2003 Chevy Maibu the theft system light comes on and blinks when the system is triggered. The car will not start and the fuel pump cuts out. You must turn key to on and have all doors closed. Keep the key to on for 10 mins til theft light turns solid and then disappears. Then turn key to start and it should fire up.

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.

This is the anti-theft PASSLOCK system. You can purchase a paslock 2 bypass system that will bypass the anti-theft othewise you will have to wait the 10 minutes with the key on the ON position and turn over immediately when anti-theft light turns off
