I swapped all mine for keyed alike Yale euro cylinders. They keys cannot be copied with out the tag (code/bar code). So much easier having all the doors the with the same key, although not so if you have a "looser" in the family who regularly looses keys! Then it gets costly!
REALLY?ABS Avocet are good.
Straight swap for eurocyls but they are snap proof. Plus they cannot be copied without the code, even if you have a key.
Just need to pop out the cyl and measure the dims from the centre to each end of the lock.
I have certainly had keys cut for the Avocet at my regular local security company and a selection of Yale Euro's as long as I had the lock and key.
As a landlord I supply 2 keys to the tenant and keep 3 (Agent, My big key ring, Safe) so I regularly need to have more cut
And Abloy 300 series padlock, took the lock and key to get another lock and a number of keys.
