The office takes another keychain, but that’s only got two full size keys and four small ones. (Made possible through similar techniques - master key system, rekeyable padlocks, etc.) I rekeyed all our filing cabinets to the same key - obviously that wouldn’t work if you had stuff where you needed to divide access up.

A Schlage “repinning” kit is about $40 on eBay (I recommend LeeLyn’s lock supply) and a “master pin” kit is about the same. It’s fun, and keeps your brain working. Schlage has an online tool to calculate the pin depths you need.

Anyway, my point is that through some relatively cheap (and fun) work you can minimize your keys so a regular keychain, comfy in your pocket and easy on your car’s ignition cylinder, carries everything you need.

This makes it easy to train several vehicles to one remote, unlock them all, jump into one, drive away, and the ones I didn’t touch relock before anyone would have a chance to mess with them.

I assumed Ford had this feature too. But you know what they say about assumptions…

I suppose I could just train myself to relock them when I start the car I’m driving, but that’s kinda a pain in the butt.

I’m almost thinking of finding someone to do some custom plastic fabrication to combine the remotes for me…

Similar “close the door, turn the key twice, tap the brakes, put your right foot in and turn yourself around” sequences are documented for programming remotes to other models of cars.

The truck key ring has a hook so i can combine it and the house keys if need be. It’s a lot of seperate key rings, but I kind of like the system, especially since i like keeping my key rings with as little bulk as possible..

That actually sounds like a great idea. The problem I have with the quick release key ring is it’s really damn long, so my motorcycle key is touching my knee when I’m driving my car. I’m used to is now, but a hook like that would minimize the length.

Also, who makes an alarm like you mention?

25+ years of the same system.

My collection has, at times, been really gnarly because I’ve wanted to have multiple sets of key rings, leading to multiple caribiners with key rings clipped into a main caribiner. The main caribiner typically gets clipped to a belt-loop.

Here is a picture with the type of clasp I have (at the top). Ignore the URL, it was the best picture I could find quickly.

It allows for full rotation, can be used one handed, is small enough to fit in pocket, and large enough to hold two/three extra rings.

I could see taking this and applying it to having sets of keys for different cars. You have your main key ring with your house/work/shop keys and one half of the quick release key ring. You put the other half on each of your car keys (have to buy an extra key ring for each set, unfortunately). When you take a car, you just grab the keys you need and connect them to the main key ring.

It also lets you leave the car keys in the car or hand them off to someone else without losing your house keys.

One other solution might be to get new keys for a ford focus, or fusion, they have the key fob built into the key, so it’s all one piece. We’ve discussed it on the explorer forum I’m on, in theory it should work, but none of us have tried it yet.

If it does? I’m buying three.
