As far as bypassing the securtiy chip, we can't tell you that one as it would assist any user on here to steal your car (or others).
When you turn the key to attempt to start it do the dash lights dim or even go out ?

My car won't crank or start you put the key in the dashboard lights would light up ain't no check engine light on nothing and where my miles said itbreading error I took my battery gets test was good


Immobiliser not disarming is a possibility or faulty ignition starter switch, wiring or connections or a faulty starter motor.

Not sure what "itbreading error" means but that might mean an immobiliser fault. I suggest you check with the vehicle handbook or give the dealer a call for the exact meaning.

A customer had a similar problem. Somehow the plastic part of the key had worked loose and the transponder chip had fallen out and been lost - about the size of a grain of rice.

Another customer left his keys on top of the microwave oven and it wiped the security code from the chip.

Besides the battery and aultanatior what would be the reson for not starting?


Alternator is not even in the starting circuit

No Crank or NoStart ---- they are different

You tested for a dead battery

If you need to jump a vehicle,don't

Find a problem-- anything & resolve it

You can ruin the electronics, jump starting or
some day you eventually will,luck only holds
out so long & you learn the hard way

Do you have spark & injector pulse while cranking

Do you have fuel pressure at the motor key on or cranking

Why no vehicle,year,motor-- shown here?

Details leading up to this,always a story that is a secret

Random times of no crank


If the security light is flashing, the chip in the key or the sensor in the key lock may be faulty. If the engine computer "sees" the right chip in the key, it allows the engine to start.
If the light is not flashing you would need to check for power at the starter when the engine will not crank. Also try cranking in neutral.

Does the starter turn over when you are trying to start before you remove the battery cables or do you have only dash lights and nothing else (not even a click). I don't believe you need a key with a chip for 2000 model, they have an ignition switch system that is basically synced to the lock cylinder and key. The ignition switch can go bad and you'll see the theft light flash on the dash. If you decide to install a new switch yourself, there is a 30minute process to reprogram the theft system to your key. It can be done by yourself, but you have to be there the whole time and need to have a battery charger hooked up while performing this operation.

try shifting to neutral to start the car. There is a neutral safety switch to prevent you from starting in gear. If the switch fails then the starter will not get the "signal" to turn over. Just moving the shifter sometimes frees up the switch. You may have a problem with your ignition switch as well. again just mass with it a bit.

lastly you may have a problem with an alarm system or ignition imobilizer, or chipped key

Do you have a Chip in the Key? if so that Could be the Problem,Ya see the chip is a resistor and if it looses its ELECTRONIC VALUE in its Case Resistance it wont start to test this Turn the Key in the ON posission then do the Screwdriver thing If it Starts Key is Good and Most Likely the Ignition (SWITCH) is Bad <<ELECTRICAL Side NOY LOCKEST SIDE For More Info Recontact Me
