They made new keys for each unit so one key could be used for both the front and back doors, which made things much simpler. They also created two separate versions of common area keys for the front and rear buildings, while making sure both worked for the shared laundry room. They were also helpful in pointing out old cylinders and handles that needed to be replaced. Everything was handled smoothly, professionally, and for a great price. I'd definitely recommend them.

From the beginning, they were awful, then, they had an issue with a credit card on file and did not reach out to me for at least a year, finally getting in touch with me telling me I owed them over $1000. This was shocking, I went ahead and paid it and told them to piss off. Fast-forward several months and they continue to send me bills, despite the fact that they do nothing, and now some moron, their name, Francesca, who clearly doesn't understand how collections work, has threatened to "begin collection procedures" because I no longer am a client with them. In addition to her being an absolute idiot, she doesn't understand contract law either. Do yourself a favor and go with a reputable company not these clowns !

I used Sentry for the past 7 years. The service was very expensive to setup, but was reliable for…read moremany years. Over the last few years, the service has dropped off along with the equipment. Alarms go off and it takes sometimes up to 5 mins to receive a call. We also started getting false alarms with several of the window sensors. We asked for a service call, first time in 6 years, and they wanted to charge us just to have someone come out. On top of that, they tried to sell us a new device saying our original version would stop working soon. They asked for $300 and a three year service contract and when I said no they just suggested I replace the batteries on the sensors. That worked for about 6 months and then again started having issues every week with false alarms. I finally decided it wasn't worth the $125/quarter service charge and called to cancel the service. I was asked to send in WRITTEN LETTER to cancel. I objected and was then told to send an email and it could take up to 30 days to cancel. When I objected again the manager became aggressive and hung up. They would not confirm that I prepaid or how much would be credited back. Avoid as there are much better options, at lower costs, with better customer service. Just look at the rest of the reviews on yelp and you will see a pattern.

This company is completely dishonest and operates like a scam. Do not trust them!!…read more From the start, the sales experience was extremely unprofessional. The representative who came to my home was rude, aggressive, and repeatedly pressured me to purchase additional equipment, and leveraged my being a single woman living along to make me feel unsafe in an attempt to purchase more equipment. Customer service has since been terrible. They sent me to a debt collection agency and have no proof to substantiate it, despite my having automatic payments set up making this impossible, and are unwilling to help me resolve the issue. When I called to speak with billing, my first call was connected over and then rang through to voicemail and the mailbox was full. On my second call, a representative refused to help, only saying I needed to work with the collection agency, and then literally hung up on me. On my third call, it was presumably screened using caller ID so my call was not answered. On my fourth call, blocking my phone number, I reached someone who was friendly but had no knowledge of the issue and could not provide answers, other than continuing to say the manager was unavailable and I'd have to work through collections. Despite multiple requests, I was never allowed to speak with a manager. I was repeatedly told that a manager named Dylan was "on customer calls" and would need at least 48 hours to respond. The lack of transparency and accountability is concerning. There is no paper or statement trail they can provide, other than stating they sent me a text message (!!!) as proof regarding this issue, despite reporting the issue to a debt collection agency, which is now significantly damaging my credit score. When I contacted ADT, they acknowledged that my account had a zero balance. Despite admitting I owed nothing, ADT cannot help and Secure24 has refused to correct the inaccurate credit reporting. Instead, they told me to resolve it with the credit bureau. If it weren't for the amount of money I spent on new equipment, I would end my service with ADT and this company immediately, and i still may rebuy everything elsewhere just so I don't have to do business with these people again or give them any more of my money. The equipment is always down, doing a software update, or something to make it appear offline, and not actually even working anyways! Do not do business with this company. They are untrustworthy, disreputable, and willing to damage a customer's credit while refusing to correct their own mistakes.
