lost keys

Today I was called out to Brentwood to a customer who had lost his keys whilst out shopping. He was able to get in but was unhappy knowing his keys were out there somewhere and someone may have picked them up and followed him to see where he lived. As a precaution I changed the night latch barrel or Yale lock as it is known and the mortise lock or Chubb lock. The customer was happy knowing that if someone had picked up his keys they could not get in his house
