We bought a door with a Guardian lock more than 15 years ago. My husband has never disassembled and greased it. A week ago, my dearest grandson Kolya lost his keys at school. I was very upset. Because the keys can be found and the door can be unlocked. My son-in-law persuaded my immediately to chance the lock. We came to the appliance shop. The required Guardian lock was in stock. The price of the lock was a welcome surprise. I thought it would be much more expensive. Thanks a lot to kind shop women. My son-in-law changed the lock on his own. I expect it will serve us for a long time.
