All Security has been quick, efficient and friendly every time I've had to use them. I just had them help me fix an interior door where the bolt had broken off inside the latch and they got it sorted in record time. The best locksmith in Park Slope and probably all of Brooklyn. Love these guys.

Friendly staff that can quickly do most keys. They do not have the equipment to make keys out of steel.

Go somewhere else, unless you want to get into an argument and leave with keys that don't work. I have been here several times and I will not be back.

I had a broken lock on my gate, and I'm so happy I found All-Security on Google and read their reviews because they handled it perfectly. Tim took my call, and Tony was available to show up immediately. Both were very courteous and professional. Tony replaced the lock with a new one that is working flawlessly. I now have two working keys where I had one broken one, an outer door that's secure, and an inner door that even opens and closes smoother. Thanks, guys. I hope I don't need anything else fixed, but if I do, I know who I'll call!

Upfront, transparent prices. Very friendly and professional service. Very quick to arrive. Opened our door within 5 minutes - no damage to the lock or our door. I definitely recommend these guys!

I stopped in here because I had a key that I needed help getting copies of. I wouldn't say they were particularly helpful. I got turned away because they told me they didn't have the key and when I asked them do you know where I could find someone who could make a copy of this key they said "I don't know I just work here." So overall I would say the customer service is top notch but probably still worth a check in.

Many locksmith listings are fake; this is the real deal - they do standard and Mul-T-Lock. Expert on site, and they also do cylinder rebuilds

Love these guys. I tried making copies of keys at 3 different hardware stories in Brooklyn, and they were all sticky or the wrong size blank. Finally decided to find a legit locksmith and success! The keys work like a dream. They're quick, reliable, affordable. Been around for 50 years. Store front is a bit dilapidated, but don't let that fool you. They're very good at what they do.

Am I dreaming? On time? Reasonably priced? Professional and courteous? Great work? Yes to all of it. Changed a messed up lock and went above and beyond, fixing our entire messed up door. Wow. I wish life was like this all the time!

Super efficient service - made it to me in less than 20 minutes and got me into an apartment I locked myself out of in even less time. Note: cash only on Sundays.

If you need any lock/keys related services GO to All-Security and ask for 'Stuart'. He is competent and courteous and responds immediately. He is part of the larger practice on Prospect Avenue and they are 24/7. I compared prices to other local providers who over priced considerably. All-Security replaces or re-keyed a Front Door Medeco cylinder with severall copies, they came on-site within 24 hrs and did a great job. The are terrific!

This place is ACES! Went in today for a new Multi-lock cylinder and extra keys for same. A very professional worker named Sturt (pronounced Stuart) suggested a way I might possibly have the old cylinder re-keyed and save a lot of money. Instead I opted for a new cylinder, as there is a magnet security feature in the new version that is not present in my old lock. Sturt was courteous, knowledgeable, and very customer focused.

He even extended the job discount to my order and he was very prompt. Can't say enough good things about this place, they are tops. Why not try them with any of your locksmith needs. You won't be disappointed with how you're treated.

I thought I had just been ripped off by a different locksmith so I called a couple others for their professional opinion. The owner was very willing to help and sounded very straightforward, ethical, and reasonably priced. I'm disappointed I didn't call him in the first place. Hope to never need a locksmith again, but if I do, will definitely call these guys.

My apartment door lock broke on my way out. Called and picked a time for them to come by, which happened to be late at night. Tony was right on time, and he found a way to disengage the lock and replace the broken component without breaking anything else, which saved me a bunch of money. Hopefully I won't need a locksmith anytime soon, but if I do, I feel much better knowing this company's in the neighborhood. Heads up, it's cash only.

I just locked myself out AND got back into my apartment, all in the time of 20 minutes! The locksmith who saved my day was very professional, calming and great. Thank you, All Security!

When I needed an extra key for my '05 Prius, I decided to go the DIY route and reprogram a new transponder I got from Amazon. The big challenge was finding a place that would cut the blank - they all said the same thing: "it's double-sided, plus we can't cut YOUR blank." This dude didn't even blink (once I agreed to absolve him of the responsibility of replacing my blank if it didn't work, natch). $5, in and out, worked perfectly. Couldn't be happier.

EXPENSIVE. OTher than that- the service was quick and great but over three hundred and fifty dollars for 3 lock changes? I was certainly paying for convenience here- next time I would shop around.

Very good locksmith who comes when he promises to and when you go to the store to make. Copies of your keys they work! Unlike keys from nearby hardware stores like Tarzian.

I don't often write reviews, but based on my experience I wholeheartedly recommend All Security Locksmiths. We had a problem with the door to our coop apartment. All Security sent someone last week who seemed to fix the problem, but shortly afterward we discovered that the lock still didn't work completely. So this week they sent a different guy who put in a lot of time to diagnose the now less obvious issue. After about an hour, he completed the repair, and management didn't charge us anything, even though the problem was more extensive than originally thought. Good job!

AVOID THE SELF ENTITLED POOR EXCUSE FOR A LOCKSMITH named Stewart et al. How hard is it to make a key copied? More so, if you call yourself an expert. Avoid him because he should know the most important thing in business which is the customer is ALWAYS RIGHT! Even when he is WRONG. The business I am sure has been long standing for years and NOAH there former locksmith has done a great job a long time and always has been above and beyond.

But to get someone who has no respect for the customer is OUTRIGHT WRONG. All I asked was for a simple key to be made $4.75 per key it's that simple do it once and do it right! #monkeybusiness

We have used All Security Locksmith to get copies of keys multiple times. They actually were the ONLY ones that were able to finally make duplicate copies of a specific key after trying multiple times with other locksmiths. We also just used them to replace the cylinder of our Multilock for our new apartment. The appointment was for 2-4 and the locksmith arrived at 225pm. He was fast and professional. If I ever need anything I'll be sure to call them. They serviced in Prospect Heights. They also accept credit cards or check.

The owner of All Security was shockingly rude to me. I've lived in the neighborhood for many years and have used this company numerous times. I'll be going elsewhere next time. I called All Security from work because my son and his babysitter were locked in our apartment. One of All Security's locksmiths had replaced our locks several weeks prior.

Ever since then, one of the locks kept sticking. It only happened every so often, and by jiggling the lock a bit, we would eventually be able to get the door open. When I first spoke to Roger, he berated me for not calling sooner. Never mind that the problem was caused by his own locksmith! By the time he called me back to tell me he could get one of his guys to my place at around 5:45 pm, our babystter had managed to get the door open.

It was around 5:30 and I was about to leave my office in Manhattan. I asked if he could send someone around 6:30, so I could be there, and he refused, saying that his guys leave at 6:00. Really?! A locksmith that doesn't provide any evening services?!

I had an awful experience with a locksmith place in Park Slope that tried to rip me off, then I called all security! Roger (the owner) takes great pride in his company. His guy Timmy was AMAZING! He was here within 20 minutes and was GREAT! Was honest about the price (which was 40% of what the other place tried to charge) and did an excellent job. I WILL NEVER USE ANYONE ELSE! These guys are the best!
