NONE! Genuine Lock Barrel for T4 - tumbled match existing keys

We will supply a T4 barrel to match your existing key. 

These barrels, springs and lift fingers are all zink platted to resist water and corrosion. Cheaper barrels rust internally and stop working after a very short time. 

Buy once with confidence. Send us your we will match the barrel to it. Better yet send us the handle and we will install it at no extra cost! This is the preferred option as sometimes the roll pin and spring break when trying to remove the barrel.
