I went in to have my truck topper key copied. I was worried that they wouldn't have the blank.but they did.saving me a lot of time and money re-keying the lock! They even went above and beyond and drilled a hole in my broken key so I could attach it to my keyring. This place has excellent customer service and the folks behind the counter know what they're doing!

This is a really good website I consider working there myself actually it's rarely good and it seems to be a universal site that everybody can use

I called to see about getting the lock on my car ignition replaced which was stuck. They informed me that they no longer provided that service, but were more than willing to give me some advice in what I could do myself to try to free the lock. I was also referred to the person that did this type work for them when they did offer roadside assistance in this type of situation.

He came out and took car of the problem as soon as he could and got my lock fixed right on the side if the road in a very professional manner. Even though Master Security Lock didn't help me directly, they were extremely helpful and did what they could do to help me out in spite of not being a client. I would recommend them to anyone for their help and professionalism.

Ask the price before getting the service! I have used Master Security Center for years, even when their shop was on Broadway. They installed 5 security doors for us many years ago. I have had good luck with the duplicate keys they have made, $3.87 each (a fare charge). BUT, this past week I was in to have an old lock rekeyed (I had the old and new key) and was charged $25.00!

I should have asked what it would cost beforehand, but did not because I never thought it would be $25. Had I known, I would have gone down to Home Depot and bought a brand new "self keying" deadbolt! Word to the wise: ask what the cost will be before requesting the service. I will now think twice before going back.

Awesome experience thanks to Brandi who cut and programmed a 2017 subaru forester blank key I bought on Amazon and brought in. This place charged me a fraction of the price their competitors quoted me over the phone. Subaru dealer wanted $400, only $50 at Master security center. Also this shop has a cool taste of the past with lots of old safes to look at while waiting.

I showed up at Master Security when I was at my wits end. Three days prior to me visiting Master Security I had been all over most of Denver trying to find a lock smith that could help me with a European key to a residential building that is no longer made. Each stop before MSC, I was told "oh yeah, we can help" and each time I left empty handed. I showed up at MSC and 4 kids basically worked feverishly for an hour trying to help.

Once they exhausted all measures Lenny (owner) was brought in. Unfortunately I ended up needing a new cylinder that had to be ordered from Israel, but in the end, MSC resolved my issue and despite it being an expensive fix, the bottom line is it got fixed and I am grateful. Professional group of guys that work there!

Great help. They get the job done fast. They are very polite and try to help any way they can. This is the second time I have had a key emergency. They had the solution that I needed. In will be back for any lock, key or door issue in the future.

Master Security is a local locksmithing company within walking distance of our house. When our garage was recently burglarized the thieves got away with a house key. One of my neighbors recommended them and I headed down there, very upset by what had happened. On their recommendation we ended up going with a multi-lock key and Emtek hardware for installing new hardware for our entire house.

That combination was fairly new to them and they ended up having some back and forth with these companies, but were very persistent until they found a solution that worked perfectly integrating the two different pieces of hardware (cylinder and doorknobs). The results are beautiful looking and we feel like we have a really terrific and beautiful, unpick-able solution that we expect will stand the test of time. I recommend Master Security Center unreservedly and wholeheartedly! You may need to be patient to get a solution like ours, but it's well worth the wait.

Went in for some keys duplicated. Considerably cheaper than Ace for auto key duplication. I've also had house keys duplicated in Lowes and got copies that didn't work. The duplicated from here worked great. The pricing was very fair and I was in and out of the place in less than 10 minutes. Support local.

Englewood Lock and Safe referred me here when they couldn't program the chip car key I purchased on Amazon. Master one upped my expectation and brought what I expect to be a universal programming computer out to my car and added the new key to my car instead. If I buy another blank car key online, will definitely go back. Per the other reviews, it does appear that the place closes early frequently. I would call before heading over there.

Any time I need key assistance I will be sure to go to Master Security. I brought my 2011 Titan here to make a copy of the microchip key and remote. When making a copy wasn't as straight forward as it needed to be, they were willing to troubleshoot in order to figure out how to get the job done. Additionally, when the act of making a copy deprogrammed my original, they were efficient at getting the problem fixed for me.

I definitely need to counter the bad review as I have used Master regularly for two years (2013-2015). Jeanine is the woman who helps me at their retail counter, rekeys my numerous locks at my work, and comes within minutes to my shop when I have an emergency. The other woman who is there when she is not is also extremely knowledgeable, pleasant and helpful. I imagine this is a mom and pop shop & it's a pleasure doing business with them. thanks
