Below is a list of locksmiths tenant(s) may call in the event of a lockout:  (names and phone numbers of local locksmiths listed here)(prior to this we would do it but only at our discretion and for a $40 fee)-----2.

That this happens sometimes and we can just request a copy fron their long term tenants, but given the challenges with their lack of cooperation, I wish I just rescheduled the closing until they got the keys.Anyhow, my realtor is now suggesting we just use a locksmith to change their locks, give them a copy and keep one for ourselves for emergency entry with notice.

I would recommend having a plumber and a locksmith who take calls 24/7.

Any tips, or contacts for locksmiths and movers to help with this in South Florida?  

One big benefit of Kwikset is the smart key system that allows you to rekey your own locks to a different key pattern with having to use a lock smith!

The whole process was about 45 day, handyman/ locksmith and about $150 court fees.

Should the locksmith work for free or should the landlord eat it?

Remove the door hardware and perhaps replace with a cover plate --- you can pick that up from a locksmith store or probably home depot, too. 

Make friends with a local locksmith, you'll need him when you have a new tenant anyway and you'll REALLY need him at eviction/lockout time.

Easier still is to call a locksmith and have them change the locks on the coin machines.
