Top service. We locked ourselves out on a holiday and called for help. The door was opened in no more than 10 minutes without any damage. Despite the holiday, the price for the work was perfectly reasonable. Additionally, we received a few good tips. All in all, I can only recommend!

Yesterday about 20 minutes before closing time, I called to ask if he could still handle my request. He was very friendly on the phone, said 'Of course, come by, we can take care of it today.' I then drove over and within no more than 2 minutes my request was completed. Very friendly, competent, likable. Very gladly again!

The last round with the dog at 10 PM and bam - forgot the keys and no phone with me. After lengthy unsuccessful attempts to somehow open the door myself, I called the locksmith GB Sicherheitstechnik with the help of a dear neighbor. The good man arrived quickly, very friendly, and opened the door without any damage. The price I paid for it was absolutely reasonable. Therefore, a big thank you and my full recommendation!

Kai Dorn

Called, briefly described the problem, and he was already there after 15 minutes. Competent advice with a very pleasant chat. Full price overview already on the phone and no nasty surprises after the work was done! Really highly recommended! Definitely professional!

Just stepped outside for a moment, light breeze, door closed. Keys are stuck inside. Mr. Gretschka and partner reacted spontaneously and friendly. After half an hour, the door was open again, without any damage. Absolute professional behavior. Costs totally acceptable. I immediately passed on the contact number to neighbors... just in case. Thank you.
