I saw a few posts on Schlage connect and secure locks. I have this lock but other posts don’t suggest a specific cylinder. About 15 years ago I was taught how to build cylinders and cut keys (i worked in access control) so I can probably do it myself though I haven’t used the skill in a while.
Initially just thought of paying a locksmith (might still do) as I can save time for other things. The locksmith said I should replace cylinders with MulTLock. My guess is they are making money on them. I do like the idea of a higher security cylinder. Any good recommendations? I need 3 deadbolts keyed the same.
