Do you mind telling what car is it? Exact model? Cause some has built-in immobiliser which will be more expensive to duplicate. Without immobiliser, it only cost less than RM100 to duplicate the key and the remote. Don't need to travel to KL. I am sure it can be done in Melaka. Try checking with those mobile locksmith in Pasar Malam. Most of them are able to duplicate key fobs. Even those with immobiliser they can duplicate as long as you have another set of the keyfob.

Ohhh wait..I think the metal piece is for the immobiliser code. That means the car does have immobiliser. Should be no problem to duplicate as long as you still have the ori key or the tag.

The pasar malam cart from which I duplicate my key actually have a shop. He goes around to pasar malam for more business. If anything, I can go to his shop. He even offered to go to my house for the duplication without extra charge. I didn't want him to go to my house for your obvious "sensitive" issue. If you feel safer going to his shop then that's fine.

Another guy works virtually from his cart parked outside a bank. He is there all the time. He has been there for many years already. He also seems reputable as a few people recommended him.

Therefore, do your homework is most important.
