My car key snapped off. I was quoted around $110 to get a replacement (and that was the cheapest quote). I rang SAS and was told that because I still had the head I could reuse the chip and it would be much cheaper (no-one else had told me this). He gave me a quote over the phone (which he stuck to) and I was able to go to them (as they were fairly close to where I live). He was friendly and professional and did the job efficiently.

Approximate cost: $50
