WOW, This place is the worst. We had 3 doors re-keyed for a business (cost over $1000) Cass said they hold our records so we can call make get keys made. Well i have been trying to get a key made for over 2 weeks and now i have a owner who's office we had to break into still has no key to his office and Cass lock is completely unresponsive. Basically if you have a big job or are going to be paying them thousands they will get back to you but if it is something little they really could care less. WORST LOCK COMPANY IN DETROIT Use Freds

AAA Locksmith
Location: Kansas City, Missouri
They won’t tell you the price until the technician gets here. I was charged $300 just to drill out a lock. Another company later told me they would have charged $80.

Arrived on the scene quickly and changed all the locks in the house even faster. Will use again without hesitation. I recommend him to many people in my line of work.

Donovan's Locksmith
Location: Wilmington, Delaware
I do not write reviews but, I was motivated to write one for Jonathan and Donovan's Locksmith!

I needed to get my 2 new truck FOBs programmed but, did not want to have to use the dealer, make an appointment, and wait! I found Donovan's Locksmith but, could not find any reviews?? I finally found one -- and, it was a bad review.

I reached out to Donovan's to confirm they program FOBs and to find out how much they charge. I was given a price that I was happy with and asked them why only 1 review -- especially since it was a bad review. Jonathan explained the situation and I decided to give them a chance. Very glad I did!!

The price he quoted was a bit more than the dealer was going to charge but, he did two FOBs for the price of one!! And, for the dealer to do it, I had to make a service appointment and wait for it to be done.

Jonathan came to my house and did it while I was able to continue working! Bottom line, the service was great and will definitely tell my friends and use him again.

As a bonus, he also cut me a new key that I could use to hide on the outside of my truck - no charge!!

Donovan's Locksmith
Location: Wilmington, Delaware
Contacted Jonathan from Donovan's Locksmith to get a couple of new FOBs programmed for my truck.

The price he quoted was a bit more than the dealer was going to charge but, he did two FOBs for the same price! And, for the dealer to do it, I had to make a service appointment and wait for it to be done.

Jonathan came to my house and did it while I was able to continue working!

Bottom line, the service was great and will definitely tell my friends and use him again.
