our local town locksmith. He took an aluminum blank, inserted and turned it with a little pressure, then proceeded to file the knicks with a triangle file. repeated that a few more times and in a minute or two, he was in. Blew my mind. Charged me 10 bucks.
I am trying to avoid drilling it since I’ll be pissed when the old owner finds the original keys and I’ll have a drilled trunk lock , repop cylinder with cheap new key.
Of course if he can’t find them that will be my only choice.
