Spare Car Keys
We provide affordable spare car key services with our mobile locksmith service. While many assume that going to the dealership is the best option, it’s often the most expensive and time-consuming. Having a spare key gives you added security and peace of mind, knowing you won’t be left stranded if your main key goes missing.
Car Key Repairs
Not all car keys require a full replacement. Snapped blades and worn plastic remote shells can often be fixed, providing a cost effective solution.

Needed a key desperately as mine fell apart. NJS came to my place of work and cut a new one and made sure the circuit board inside worked also. Can not give enough praise and thanks. Would totally recommend this company. Many thanks. Craig

10/10 – Highly recommended While every other locksmith in the area quoted 3–5 working days just to attempt a repair, NJS Auto resolved everything within 2 hours. Their mobile service really makes the difference. My car key had snapped in half and I couldn’t start the engine or move the car from where it was parked. NJS drove out to my location and sorted the key on the spot. The technician also kindly checked the condition of my car battery, which seemed faulty, and didn’t charge anything extra for it — a small gesture that says a lot about their professionalism and customer care.

Nick was really helpful! I was quoted stupid amounts to fix my key. He was reasonable and booked me in rather than I’ll make some calls which was what I had elsewhere. Highly recommend! A very happy customer!
