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.

Bike not starting


Do a plug elimination test, take the lead off one plug at a time and turn over the engine. If one particular plug being disconnected makes no difference then that plug is probably not firing. In this case try replacing the plugs.

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.

My 2003 chevy malibu cranks but wont start. battery is good and altenator is good


To clarify - - if the engine cranks the battery and starter are ok.
The alternator does not come into play until the engine is running.
If it cranks but won't start, you have to figure out if you are missing fuel to the injectors or spark to the plugs to proceed.
A mechanic would check that and if there are any trouble codes stored in the computer.

Jaguar x type battery dead


What year and engine size is this 2008 jaguar x type?

Are you sure the battery is good, did you have it tested, next if battery is good and you can see bright headlights when you turn them on then i would look at the fuses, if you jump started it you may have blown a fuse.

when you say no ignition what do you mean? are the dash lights coming on when you turn the key?

Is the problem that you have no knd of power to car or every thing lights up but nothing happens when you try to crank engine, or does engine crank (SPIN OVER) but not start up ?

let me know the answers to these questions and i will help you. good day

Have a problem starting from day to day. think a genric key could be a problem. runs fine once it starts. never had a key with a chip. disconnect batt. to reset computer and all is fine!!! how can this...


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.
