I'd like a zap 'n lock too! my sister has 3 sliding glass doors, garage door, 2 mostly glass doors and a huge wooden front door. they all 'ding' if anyone opens them. she does have security hook up so not sure how that works at night. spect she still has to lock 'em all and set the 'thingy'. actually, she's behind locked gates too... she only unlocks a door if she's expecting someone - usually me. I have a gate opener! my gun is always loaded! it would give me a second or 2 to get it tho. it's always within about 3' at night. I like the idea that if one of the kids/gkids were here (not real likely with little gkids) that I could lock the door tho. i didn't bother with the deadbolt on it. the other doors got deadbolt's with the flipper on the inside. that's needed for me if I need to get out fast AND there is no glass area close to the doors. tho someone could break in thru a window and flip it unlocked. I do think they'd pick somewhere else tho - with dogs barking here... besides - they could just open the patio door! I found some satin nickel I liked - it didn't look like the satin nickel at home depot. that looked like it was coated in a thick clear varnish. weird thing is I was looking at something online today and they even said the satin nickel was covered in clear varnish! ugh! i bought the curved lever for my bedroom and the hall bath and 2 cheaper ones with a straight levers in satin chrome for the back 2 bedrooms. the local hdwr I went to the other morning only had 2 deadbolts and the 2 curved lever handles so went to another local hardware in the afternoon and found another deadbolt and 2 more handles that I like better than the curved ones... dang. I do still need a few more lever handles so will go back to the 2nd hardware for those i think. i was thinking that the security screen doors might look weird with a curved handle on them so had the guy just put the 2 straight ones i'd bought for the back bedrooms on the security doors. the metal color is a bit off to the deadbolt but it was better to have handles on the security doors than the back bedrooms at this time. might switch them around when i get the new handles tho. I do like the look of the stainless. at hardware #1 I found a stainless kitchen faucet i liked for 118.00! imagine that! and they have a bathroom sink faucet for 88.00 I think it was. stainless also and 1 handle. I couldn't believe I saw some I like in SS for that little! one is Delta and 1 is PPhister I think.

cabinetparts.com has a great search tool... it returned 106 hits for 96mm and chrome. However, in case you can't find a chrome handle you love-- I urge you to reconsider using a polished nickel. I was hesitant to mix finishes, but threads on here showed me it was fine. So now I have PN handles, a chrome faucet, and SS appliances, and it all looks fine together. Some brands' PN is cooler than others so you may want to do samples first. (I ordered a bunch of samples from Lowe's and HD, then price-shopped for purchase after I picked my favorite). Your highland ridge handles are gorgeous; they were on our short list. We went with jeffrey alexander belcastel (purchased through A & H Turf, for well within your budget)

Patio Door Lock Strike. Call these guys, if anyone has it t will be these guys.

I bought beautiful handmade bronze hardware for my previous kitchen from this company. https://www.pruskinhardware.com/ They customized the length of one of their knob designs for my project. They would definitely be able to make something like the pull in the photo. The question then becomes how much time and money do you want to put into the project. I think Rocky Mountain Hardware will do custom projects too.
