SlotenmakerSnel 

Tony has opened the door for me very fast and he was a very kind guy he did everything very well. I am very satisfied with his work.

Good job from Hamza. He quickly resolved our door lock. Super friendly too.

Bad information and very costly.
Not recommended to use

Mert was very helpful. I was very please with how quickly he came. He did a very good job and I am very pleased.

Called at 9:38am as a “smart” lock has failed. Was told 30-45 mins later and they would call 20 mins before arriving. Called them after 1 hour, was told they would call me back - didn’t. Same after 1 hour 20 and then 30. Eventually they called back to say the person is sick and not working today. What an absolute joke of a company. Then I see the other reviews here and maybe I escaped

Excellent work! Issue resolved promptly.

Fast and efficient! Problem solved quickly.

Reliable and efficient service, I feel much safer in my home now.

Great and prompt service, resolved the situation in a very efficient way

Roy is a very good mechanic.service was excellent

The worst service we have ever received. Ridiculously overcharged and the lock very poorly installed. It pulled away from the door. Customer service full of promises but no one has come back to fix it. So disappointing. The worst service delivery we have had! They take advantage of you and lie about prices.

What a SCAM! And a pity that so many have fallen for it.
Firstly, they sent an intern who didn't know lock picking for a lockpicking job. He took one look at the lock and said it has to be drilled. I said no. That I have a key to the back door in Amsterdam (I lied). He then got worried ....thought for a moment and then said I can use a special plastic card and try. I said ok. It was a normal plastic sheet! He then said it would cost 180 euros, I said no and that I would pay his arriving charges of 35. He said that I also have to pay cancellation charges which was clearly mentioned as 0 on the phone call.
He finally said he would do it for 120 all inclusive. He couldn't slide it properly and had to call the real locksmith and ask for directions!!!!! All he did was slide a card around the door. And then asked me for 150 after agreeing to 120!! SCAM SCAM SCAM!!!!!!

Instead go for Slotenmakemk, it is 67 euros flat. And no headaches.

This company is unethical and my experience was exceptionally poor. They get negative reviews removed from other sites: I'm hoping that TrustPilot is ethical enough to not remove reviews.
I locked myself out of my apartment, and I called their call centre. It was winter and very cold. They said they would arrive within 30 minutes: they did not. Kept calling and they kept saying they would arrive. They ended up being very late.
The locksmith they sent couldn't get my door open, and ended up damaging my door. He did install a new lock, but the work was incredibly shoddy: the door wasn't secure. He would not leave until I paid him, so I figured I would pay the huge bill and get him out, then deal with it later. A reputable company would take one look and sort it out, surely.
I tried to contact them to get them to make it right, and they said they would, but never did. They kept me waiting for over a week with a door that wasn't secured properly, then got upset when I asked them to deal with it promtly. Absolutely unbelievable that this behaviour is legal in this country.
I ended up having to replace the lock and fix the door at my own expense.
Edited to respond to their response: they had multiple opportunities to fix this situation, and they chose not to. I had to fix it on my own: I am a woman living alone and it wasn't safe to live in a home with an unsecured door. They chose not to take any action.

Attention: If the invoice looks like a rip-off, do not pay it on the spot! It says:
"Bij betaling bent u akkoord gegaan met de bovengenoemde prijzen en werkzaamheden."

I guess what they do is still legal, but certainly not ethical.
My backpack was stolen on a Sunday evening, and along with it my apartment keys. Needed to get in my place, so called SlotenmakerSnel.
Over the phone they said the service starts from 90-120 euros without BTW and it can go up depending on the situation. Well, it went higher, way higher. The agent arrived in 45 minutes.

The guy said I have "a good lock", there is no other way, but to drill. He said it'd be 250 euros in total... I accepted it.
Then it turned out that a new lock is not in the price. He offered to give some "high quality" lock for 110 euros. Since I couldn't leave the door without a lock, I had to go with it as well.
The model he installed, DOM Plura (with 3 keys) looks like it costs 20 euros in total.

Then the invoice came. First of all, he didn't mention that these prices would be without BTW, even then, these didn't conform to what he previously said... and the cost for that lock is just ridiculous.

I feel I've been ripped off, and taken advantage of, because I was in a situation that I had no other way out.

I understand that emergency service on a Sunday night is not cheap, however I certainly wouldn't expect it to be 496 euros. I have not had other choice but to pay, given the circumstances.

I reached out to their customer service, their answer was that there is nothing wrong with the invoice and that I've accepted the terms by paying it!
