I purchased the Ultion main door lock in 2023 and was very pleased with its performance. I also ordered two additional coded keys, which worked flawlessly. In 2025, I added two patio door locks with thumbturns and an extra key. When I initially placed an order for standard locks, I called to cancel and reorder the thumbturn versions instead. The process was very smooth—after placing the first order, I called back within an hour to cancel and replace it without any issues.

The entire order arrived the next day. I fitted the locks myself—perfect fit—and all 5 keys arrived too. All four of my original keys were upgraded to a newer model free of charge. I've checked—both old and new keys open the new locks, but I’ll be using the new ones and putting the old ones aside.

Overall, I am highly satisfied with the quality, security, and customer service, and I confidently give Ultion a 5-star rating.
