The Home Depot

So whats the question your trying to have answer? Maybe I can help....

They take all precautions to protect there customers

It's so sad to hear jon.. But you can always let the manager know that you call customer service and raise your concern there if he's u fair with you. But, usually they are very fair with their customers.

Yes

Correct, keys are copied, locks need to be worked on by a locksmith

They do offer assembly on certain items, not sure if this would qualify and or cost. Best bet is to call and ask. If not im sure you could find a third party on your own.

Yes

Yes they do. I believe you can find more information on the Home Depot website or visit the store and go to the contractor counter. Rental equipment varies by store and depends on what you want to rent.

I have seen it, but you should call to make sure they still have it
