Im looking to reburb my door locks but was wondering how I go about getting more keys cut if my current one is very worn? After using it to turn the ignition on a work machine it became really notchy to unlock from the boot (I have to wiggle back and forth now)
Just wondering if the bmw dealership process of cutting keys will just mimic my current key or will I get one that has edges like it should?

if your locks havnt changed bmw should have them no problem alwasy worth getting a new one cut cost me £7 each for me from non bmw key cutters

absolutley
