ABS Cylinder that supports key-in unlock?

[twixx]

Does anyone know if ABS have a 35/35 Euro cylinder that supports key-in unlocking?

Ie. When a key is left in from the inside, someone with a key can still unlock from the outside?

I currently have ABS MK3 and on rare occasions I’ve had them unlock when a key is left in, but this is definitely more luck than anything else!

We have one that is deeper and we still need to pull the key out on the inside slightly to get the key in from the outside.

Unless....your inside key is in the right position to be pushed out of the lock by the incoming key?

Would a thumb turn cylinder work for you? No need to find keys in case of an emergency, and if that's where you like to keep your keys you can hang the ring on the thumb turn

Already have a thumb turn, so yes… but the ABS thumb turn/knob is it really chunky and too chunky for any smart lock I’m aware of

Could be wrong, but not sure it works like that?

In theory, with a smart lock, there would be zero need for a key at all… but, I need to pass the wife acceptance test.

Maybe the way around it is to get a 35/ 45 with the 45 inside

Is it really the barrel length that dictates key-in, unlock?

The way the cylinders that support it ‘market it’, suggest it’s a feature/function they’ve designed.

Oh right, I didn't know that, i thought it was just the length of the key hitting the end of the other one preventing it from going all the way in. I didn't know it was a feature and thought it was just an accident if the design

You could be right. I’m no expert.

Just seems too simple? (Especially when others claim it to be a feature).

Google says;

A "key-in unlock cylinder" refers to a type of lock cylinder where a key can be inserted and turned from both sides of the door, even when another key is already inserted and turned on the opposite side. This is often referred to as a "double cylinder lock" or a lock with an "emergency function". It's commonly used in situations where you might want to leave a key in the inside of the door for convenience or in situations where access is needed from both sides, even when the door is locked from the inside.

I'm not sure I understand the chunky complaint. Are you saying you're retrofitting some kind of motor that is capable of turning a slim key, but the thumb turn is too wide to fit into the slot on the motor?

Exactly.

Pretty sure a grinder could sort that problem out in about 2 minutes; what's to lose by trying a reshape, if you were going to bin the thumb turn you have anyway?

ps; if you don't have an angle grinder, do give careful consideration to whether you should buy one. I use mine daily and do consider it one of the most useful tools I own but i do also strongly consider it one of the most dangerous tools I own (and it's a battery one, generally less aggressive than an electric one, the concern being that if purchasing a tool for a one off job, one might buy the cheaper, more aggressive, electric version)

If you've never used a grinder before I'd recommend to buy or borrow a bench grinder instead; they're much less likely to cause an injury. You also, alternatively, could seek out someone locally who does have one and pay them some small amount of money to reshape your thumb turn. I'd do it for nothing if you wanted to post it me together with an SAE and the dimensions

It'd be a longer job but a hacksaw and file would also turn out a similar result, I expect..

 

[twixx]

Haha, I’m absolutely not against that. But would probably order a spare 35/35 just in case it went south.

I’d probably use my dremel over my grinder too. I absolutely hate my grinder as it scares me to death.

I’d probably also grind the knob turn to a more key like shape if I was going to take this approach. Was just kinda wondering/hoping someone might have been here before, and managed to get the knob off.

 

[robinbanks]

Dremel might take a while, but overall would definitely be a safer option. Since buying a battery angle grinder I've never wanted to use an AC one ever again.
The higher speed, heavier armature (more momentum), cable to get snagged on anythingand everything, even the noise they make.. genuinely perturb me

The thumb turns I have do seem to have a small bruv screw that I suspect would make the knob come off so the peg could be reshaped but I'd probably try to keep the knob if doing as you propose
