Enabling and blocking the key programming function without a special tool
Enabling this function allows you to register a key without a special tool (WDS or equivalent)
Locking this feature prevents drivers from being able to reprogram keys on vehicles owned by car rental companies or other companies with large fleets.
Connect a special tool (WDS or equivalent).
Using a valid or new key, turn the ignition switch to the ON position.
Confirm access to the security system. Select "Enable / disable the key reprogramming function without using a special tool."
Enable:
– key registration can be performed without a special device (WDS or equivalent).
Block:
– key registration can only be performed with a special device (WDS or equivalent).
This feature is enabled when the vehicle is handed over to a customer.
Security Access Procedure
To clear the ignition key code or disable the key programming function lock without a tool, you must confirm access to the security system.
Connect a special tool (WDS or equivalent).
Choose Toolkit, Bodywork, Safety, then PATS Features (in that order).
A special device reads the shutdown code depending on the intended procedure.
Use the official Mazda website to obtain an enable code that matches the disable code.
For details on how to perform this procedure, see Service Information No. A001/02.
Enter the activation code into the special tool (WDS or equivalent).
Removing and installing the ignition lock
Remove the lock only to replace it. In this case, immobilizer reprogramming is not required.
Disconnect the negative cable from the battery.
Remove the steering column trim.
Disconnect the connector and remove the lock (fig. 1).
Immobilizer reprogramming procedure
If you still cannot reprogram the immobilizer, check the number of working keys.
Replace the key or reprogram with the addition of keys.
To make a duplicate key or replace an immobilizer element (key and/or PCM), the customer must bring all keys to the dealer.
This is because pre-programmed key IDs are erased from the PCM when reprogrammed.
Do not transfer the PCM from another vehicle.
Otherwise, the engine will not start. Do not replace the PCM with a new one for troubleshooting purposes.
The key ID and code word will be programmed into the new unit and cannot be used later for other vehicles, even if you find out that the old unit is good.
The immobilizer cannot be disabled.
Check that all registered keys allow the engine to be started after the reprogramming procedure.
Wait at least 5 seconds before using the next key.
When the client does not need to register more than two keys, the following operations may be terminated after registering two keys.
