I have a Yale smart lock on the deadbolt, and the locksmith suggested that he rekey the doorknob so that any key would open it.

A plus if they can refer a lock smith, to change the locks.It's an eviction, but first going towards the route of Cash for keys, with my attorney on stand by if they does not prove fruitful.Thanks

For example, we require all locks be rekeyed at tenant changeover.

Once the Sheriff shows up in their riot gear with the team of movers and locksmith (whom you must hire as well), most if not all leave in peace.   

On the lock-out date, next Wednesday, I plan on having a locksmith there at the same time the sheriff arrives, as well as someone to appraise the property inside, check for vandalism and secure against squatters.3. 

Hello Boston Real Estate Investors - I am looking for a good reputable and honest locksmith in the Quincy MA area. (02169).

I will gladly refer you to handypersons, electricians, plumbers, roofers, locksmiths, or whatever else you need.

If the key has been changed, then a locksmith will open it and the charges passed on to the tenant. 

Wouldn't you re-key all the locks after a tenant moves out anyway?
