Spare keys And Lost Key Replacement
Having a spare key made while you still have one working is strongly recommended. Programming an additional key at this stage is quicker, less invasive, and far more cost-effective.
When all keys are lost, the job becomes much more involved. The immobiliser control unit must be accessed to program new keys, which often requires full dashboard removal. This significantly increases the time and labour needed compared to making a spare in advance.
Although both spare key programming and lost key replacement can still be completed at a fraction of dealership prices, having a spare key made early can help you avoid unnecessary disruption and a more complex repair later on.
Never the less, if you've completely lost your keys ,give us a call and we can be out same day to get these replaced.

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!
