NP200 spare key replacement.

I had my vehicle panelbeated and the door locks replaced due to attempted theft. The finish on the vehicle was excellent. A month after the vehicle was completed I had a problem where I had locked my keys in the vehicle at my home. I had then used my spare keys and to my astonishment I noticed that the spare keys doesn't open the vehicle. I had contact DCP numerously for assistance on the replacement set as I was told they will ensure the locks are done to the key I had left with the vehicle. I made.Many calls and was given the run around as to being told they will call back but that doesn't happen.
