Frequently Asked Questions on Smart Proximity Keys
Clear technical guidance from our Grantham workshop technicians.
Do smart proximity keys still have a physical metal key inside?
Yes, absolutely. Concealed inside every smart key is a high-security emergency mechanical blade (such as HU101, HU66, or SIP22). We decode and CNC-cut this blade to your door lock cylinder. If your vehicle’s main battery or the key's CR2032 battery ever discharges completely, you can slide out the blade, remove the door handle cap, and unlock the vehicle manually.
Will my existing smart key still work?
Absolutely. We program the new key alongside your existing one so both keys operate all locks and start the vehicle seamlessly.
How much does a duplicate smart key cost?
Proximity smart keys generally range between £130 and £195 depending on the make and model. This includes the smart fob, laser-cut emergency blade, programming, and driveway visit in Grantham.
