Look at What Ernie’s Customers Have to Say


I’ve been here several times in the last year. Both for my office and for personal. Regular keys and SPECIAL KEYS ALWAYS WORK. That’s important. Everyone is very helpful.

~Joe D. (Washington DC)          



Sure. You can say, “What’s the big deal about a lock and key company?” Plenty.
#1: Many don’t open until around 10:00 or later and when you need a key or a lock first thing it’s nice to know this place opens at 8am.
#2: The keys they make always fit and always work.
#3: They have a ton of key blanks and will even replace Medeco and other specialty keys including those new fangled car key thingies.
#4: Tons of different kinds of locks for lots of different uses.
#5: Friendly, knowledgeable staff. They know what the heck they’re doing.

~Ken M. (Glenn Dale, MD)          



I have been at Ernies Lock Shop at least a couple of times. I have found the proprietor pleasant, helpful and knowledgeable. This is a real shop with real inventory – hard to find these days.

Daniel S. (Madison, WI)          



The keys they made for me worked the first time and every time… as opposed to the keys from the hardware store which always stick. It is worth the slightly higher price to get the job done right.
