OBD protection for van security
Reduce unauthorised access to a vehicle diagnostic connection.
OBD protection — help prevent unauthorised key coding
The OBD diagnostic socket gives technicians access to vehicle systems. Criminals may also try to use diagnostic equipment to programme a new key. An appropriate OBD protection device restricts unauthorised access or use of that connection, adding another layer of protection against key-programming theft.

How it works
Depending on the vehicle, protection may secure, isolate or block access to the diagnostic connection. Authorised access can be restored when servicing or diagnostics are needed. Suitability varies by make, model and security system; no single device guarantees prevention of every theft method.
Select OBD Protection in the lock enquiry form and tell us your van model for advice.
