How do you get padlocks rekeyed?

Question

We have like twenty locks with four different keys.It's a pain to go thru each key for each lock.By the way,they're Master locks.

Answer 1

It's cheaper (by far!) just to get new locks that match. You might try color coding the keys to the locks. Get some colored electrical tape. Match the keys to the locks, so that your 'red' key and 'red' locks all go together. Just wrap a small piece around the hoop in the lock and put another piece on the end of the key.

Answer 2

You can remove the locks and take them to a locksmith for re-keying.
