Previous key number to match, what does this mean?

We can key the lock on the Blast Alert to a specific key number to match a key number you have previously purchased. Just fill in the key number you want in the optional box and we will key the Blast Alert to work with that key number!

If you do not know your key number to match, just leave this box blank and we will match it to your previous order. If you do not want the Blast Alert matched to your previous order, choose the "Keyed to New Key Number" option rather than the "Keyed to Existing Key Number" option.

If you have questions, please give us a call.
