One friend from Spain sent us a very detailed inquiry. He originally installed a traditional mechanical lock, and now he wants to upgrade to a smart fingerprint and password door lock. He gave us clear door and lock pictures as well as his lock drawing for us to measure. He is a real door lock expert.
This is a typical example of an OEM that door lock is to be installed on an old door. We have a rich experience in the projects for old locks upgrading, so we can handle this case
Per the cylinder size and the door direction, we recommended that our fingerprint and password door lock model 202 should be matched, of course, we made necessary adjustments about the cylinder.
Nice to meet you！We will contact you as soon as we receive your information. Email:email@example.com
