Considering that 1995, it has actually been a legal requirement in the United Kingdom for all brand-new cars to be fitted with an immobiliser system.

3. EEPROM/Soldering
For high-security cars or when all secrets are lost, the service technician may require to remove an electronic module from the car, such as the immobiliser or the ECU.

FREQUENTLY ASKED QUESTION: Car Key Programming

Q: How long does the programming process take?A: For a basic OBD-II program, the procedure usually takes in between 30 and 60 minutes. Nevertheless, if the locksmith professional has to perform EEPROM work or "all secrets lost" healing, it can take numerous hours.
Q: If I purchase a second-hand key from eBay, can it be configured?A: This is dangerous. Many modern-day keys are "locked" to a particular vehicle's VIN once set. In addition, the transponder chips in inexpensive aftermarket keys frequently fail or are the wrong frequency for the UK market (which usually runs on 433MHz).
Q: Does the brand-new key need to be cut first?A: Yes. For cars with a physical ignition or a hidden emergency situation blade (in clever keys), the mechanical cutting must be done to match the locks before or throughout the programming stage.
