Can anyone recommend a good car keys locksmith in London.
Looking to get a spare key for 2 of my cars...of course has to work like a regular car key from the manufacturer

I've called around some places based on Google searches for quotes...
I've been quoted anywhere from $200-$400 to get a spare key for both cars
Some of these places when I called seemed a little shady...

So I'd like to see if anyone here has any good experiences or stay away from certain locksmiths..

Thanks!
