OK here's one for the brains trust.
I have an outdoor gate. I've fitted an electric striker to the gate with a release button and some other bits and pieces.
Now I need to get into the guts and stop the handles retracting the tongue on the gate.
There are 2 small holes on the inside of the handles, and when poked they move a plastic bit out. Nothing further seems to happen.
There is 1 small hole on the outside of 1 handle, I've poked it with wire, small allen keys, bobby pins, straightened fork and I can't make anything happen.
Also one of the cover rings (nearest the gate itself) will come off a little, but I can't see any hidden screws under it.
No access via tongue area, I've drilled out the pop rivets on the cover place, and no go that way.
Any ideas?

It has to have something to do with those holes, maybe try pushing into them both at the same time whilst slightly pulling the handle out or even rotate the handle whist pulling it.... Then repeat on other side.
You will have a hex socket grub screw inside those holes, put in a small allen key straight as you can to try and get it into the head, size will be hard to determine.
The handles will come off once you loosen the grub screws, then lever or unscrew off the round covers.
Remove the escutcheon plate with the latch in , then push the latch in and replace with a new (fabricated from something in ya shed) escutcheon plate with no hole for the latch. push in place and screw back in , Problem fixed?
Mate,
Insert the key and turn 90 degrees, then try and push a pin into the hole on the latch side of the handle. Handle should pull out, then remove the cover plate. There should be 2 screws underneath to take the whole lot off.
The pin part is tricky sometimes. It will be easier if you hold your tounge the right way.
Cordless drill 6 mm drill bit. Proceed to drill every little screw and lever to pieces any hole you can drill drill it. Eventually drill bit will snap off and by this stage it will go into

Either way its going to be painful , you will then throw the cordless drill on the ground, destroying it. You will swear whilst doing this as you realise the cordless was worth 200 bucks. The drill bit 2 bucks and the lock mechanism probably 20 bucks. The look from the miss us for swearing in front of the kids will cost you 200 bucks ( fancy dinner) the kids laughing at you while blood spurts out of your drill hole in your

B palm of hand .....priceless. Best advice pay a locksmith and watch him whilst drinking a beer offering him expert advice... That's what I do

Voted "most likely scenario"
So far my dad, my wife, my wife's dad, and even my 2yr old has had a go, with no luck.

You might be on the winner there - haven't tried turning the key yet. Didn't think of that.

should be much like the above, generally you cannot take a doorlock apart- or the handle off- unless it is unlocked.
[no point having a lock that can be easily taken apart from the outside.]
The key barrel has an eccentric cam thingo which blocks the spring loaded pin that is in the side of the handle when it is in the locked position
[unless it was assembled incorrectly-and this is pretty common!]
If you push a small punch or allen key into the hole and keep pressure on it- then turn the key you will find a point where the pin slides in further.
This is the time to yank back on the handle and land flat on your bum to entertain the assembled onlookers.
Often the spring and handle have built up dirt and traces of corrosion built up inside- which can make it difficult.

The "inside" doorhandle [with the pushbutton] should only need the security pin pushed in to release the handle.
The escutcheon plates should have a single hole on the outside edge- this is for a "C" spanner to fit into for tightening and loosening, but the front plate should not unscrew as it has a spring loaded pin preventing it from turning.
The rear escutcheon plate [inside] should unscrew- you can use a punch and hammer to give it a few gentle taps to get it turning.
If its all too hard, sling me an airfare and I dont mind doing the job for you!
