I went in to get a couple locks keyed together. They quoted me $ 25 /ea or $ 50 for both. Actually, one did not need it, since the key would fit the lock to start with, but the guy didnt mention that part. So I felt like they were trying to rip me off, the lock manufacturer Company told me to go to Home Depot and they would do it for $ 5 total, so that’s what I did. So, it appears that they are trying to crack the safe on your wallet. Cavet Emptor.
