Something is not right with this story!
#1. Ace locks are rarely used to protect $ , as most thieves understand very well how to by pass them,
They are most likely a different make of lock.
#2. $2000 to R&R the locks ....!!!!!! Give me a break ! Either you gave us or the lockie the wrong info.
For $2K you can Fly me to your location, hire a limo to drive me around, keep me in the finest hotel in the state, and still end up with
better locks than you have now.
#3. You are a business man with an ongoing business but you want to "play" with opening "vending locks"???? HMMMMMMM
My recommendation would be call the company that supplies parts to the car wash equipment and get a referral to the service company they use.
You can be sure you are not the first car wash owner to have a similar problem ( i.e. lost / missing keys)
Ask them to leave the old locks so you have some to play with.
