I'm moving soon. My new landlord who just bought the house said he's replacing the front door lock because the deadbolt lock is rusty and doesn't work.

He doesn't want to replace locks on the back entry door and inner apartment door because it is expensive. I'm concerned that previous owners/tenants may have copies of keys.

One entry has a Segal deadbolt and also a doorknob lock which has no name printed on it.

The inner door has a lock with no name and near the knob is an old-fashioned keyhole (like for a skeleton key).

I had heard that it can be less expensive to "rekey" a lock than to replace the whole lock.

I'm wondering: are there certain things one can see by looking at a lock that indicate it could be rekeyed? Is rekeying something I could do or does one need a professional locksmith with special tools for that?

Thanks,
Donna
