You can't bypass an immobilizer as it is all computer controlled and monitors the security modules. You have to fix the issue not find a way around it.

How do reset the keyless system MX 5 Miata Forum

Dom you have a manual?
Even if you do not reset, the car should start (The Jeep Grand Cherokee start anyway), but maybe the Mazda won"t.
At the oil filter cover, did you find some wire, switch or something electrical?

no
resetting the ecm is with a scan tool
but you can use the scan tool to find the failed sensor preventing it from starting

Hi there,

Your Mazda 6 keys have transponders built in and only the correct key I.D. will activate your vehicle's immobilizer.

I'm at a loss as to how changing a fan belt could have altered your vehicle's immobilizer system - are you absolutely certain the garage hasn't disturbed any of the electronics?

First, we need to establish whether your vehicle's immobilizer still considers your keys as valid.

- Insert Key # 1 and turn ignition to ON (do not start).
Observe the "Security" light in the cluster - it should illuminate, then turn off after approx. 3 seconds. If this works, then Key # 1 is considered still vaild.
- quickly turn Key 1 back to LOCK position and remove key.

Wait 5 seconds...

- Insert Key # 2 and turn ignition to ON (do not start).
Observe the "Security" light in the cluster - it should illuminate, then turn off after approx. 3 seconds. If this works, then Key # 2 is considered still vaild.

Note: if Security light does not behave as above and keys still won't start your car, then your keys are no longer validated by the PCM

If this is the case, then unfortunately unlike other manufacturers, only Mazda will be able to re-program your key's ID into your vehicle's PCM. Contact your local Mazda Dealership to discuss.


Regards,

Scott
