For high-security automobiles or when all secrets are lost, the technician might need to eliminate an electronic module from the car, such as the immobiliser or the ECU.

Attempting to set a key without the correct tools can lead to the automobile’s ECU being locked or corrupted.

Q: How long does the programming procedure take?A: For a basic OBD-II program, the procedure typically takes in between 30 and 60 minutes. However, if the locksmith has to perform EEPROM work or “all secrets lost” recovery, it can take several hours.

Furthermore, the transponder chips in inexpensive aftermarket keys often stop working or are the incorrect frequency for the UK market (which usually runs on 433MHz).

Q: Does the new key requirement to be cut first?A: Yes. For automobiles with a physical ignition or a concealed emergency blade (in clever secrets), the mechanical cutting needs to be done to match the locks before or throughout the programming stage.
