Locksmithing Canopy Doors

Time: 1hr

Well it just goes to prove that when you’re building an airplane you basically need to know “everything” :-). Never did I imagine that my locksmithing skills would have been used on my airplane, but to get the two canopy door locks to use the same key required a bit of that. When I was putting together the door locks I noticed that the keys had different codes on them (TEM30 and TEM19). The codes are for knowing what key to get if you loose them. The code is also on the outside of the lock. I found that the locks are made by Hudson, but couldn’t find any replacement lock cores or a rekey kit (though I did find a rekey kit later in my searches). I opted to order a new set of “T” handles from Amazon that looked exactly like the ones that TAF supplies. The new handles were keyed the same. There are no manufacturer markings on the TAF supplied handles so it’s anyone’s guess as to who actually makes them. In any case the replacement handles came and while they looked exactly the same they were a little larger diameter so if I wanted to use them as a direct swap out I’d have to do some more drilling which I wasn’t too keen on.

After some head scratching and thinking maybe just go to a locksmith or email TAF about getting matching locks (but where’s the fun in that?) I figured out how to get the lock core out of the replacement Bauer locks so that I could use the wafers inside to rekey the TAF locks to ¬†use the same key. My persistence paid off and I now have both doors using the same key… now for that luggage door :-). Actually the luggage door has a bit different key (it reversible) so no way to rekey it to get it to work, I don’t think. I might be able to replace the lock with a Hudson or Bauer (the replacement lock I bought). I guess any single sided wafer type lock would work.

The TAF (Hudson) lock core is on the bottom and the replacement (Bauer) lock is on the top. Once I got the Bauer key core out of the lock assembly I just pulled the wafers out and put them into the Hudson core in the same order. The trick to removing the Bauer key core is you need to press in the sixth wafer that allows the whole core to be removed. The TAF locks are a little more secure since you need to remove the parts on the inside of the door and remove the whole handle to get the core out. Either way none of the locks are really all the secure.
