Lost key to 2002 Mustang 3.8 what's the cheapest fastest way to fix? Can I bypass the anti theft system? Buy new ignition and key will that work?

Hi,

Saturn was owned by general motors, so I would recommend calling GM and asking them to email you the diagram. Their phone number is 1 (800) 462-8782.

Thank you.

you dont and if had key cut should work or did you just have a non chip key cut which wont work

From my experience...
A non PATS coded key SHOULD not turn the STARTER...!

If ANTI-THEFT were invoked... you can attain a not start condition which the Owners Manual says must be cleared by the dealer.

A working PATS key should disable the anti theft... by turning the ignition on... ELSE try your other key.

The SecuriLock [PATS]
passive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.

Anti THEFT cuts off fuel pump and the ignition module. That is what it is for. The theft light on the dash should be on too. Something tripped the anti-theft system Try resetting the anti-theft module by locking and unlocking the drivers door with the key.

yes as when you change an ignition switch it has to be sync to the computer so it knows the correct keys are being used and the car is not being stolen.

So I can use my 2001 Mustang 4.6 L that changed the ignition out and then I changed the computer out now that's flashing or it won't let it start and it starts to die

no the key needs to be programed for now disconnect your ground cable on the battery for a couple minutes then try to restart it

The chip is in the key. Either the key has lost it's program or the transceiver is not recognising the key. Try another key if you have one.
