Going to glue /adhere one of those velcro hide-a-key things to the underside of my sons car. The car is very hard to break into if he locks his key in it. Anyone got a favorite epoxy that they use for these types of applications. Prefer something that sets/cures fast.

Thanks

A different option for a spare that I really like is a wallet key. You can have a key made that's flat and doesn't have a blob on the end that fits in wallet.

I have a factory wallet key that came with my truck and it's definitely come in handy.

Get one of the magnetic hide-a-key holders. More than likely the epoxy will eventually let go and the key will be gone. If not a magnetic holder then rig up a way to zip tie it under the car.

Hose clamps. They won't degrade like epoxy or weather out like zip ties.

Been using magnetic holders for a long time. There are lots of nooks and crannies under the vehicle where they can be hidden and never fall out. I might have to get dirty crawling under the vehicle, but I promise no one else will see it and it won't fall out.

With the security system in my Dodge Ram, a key without the built-in remote will set off the alarm every time. They can't program it otherwise. A honking horn is better than having to break a window, though. I had a spare key made that will open the doors and start the truck but it sure wakes up the neighborhood.

With any kind of box under the vehicle, I suggest wrapping the key in Saran Wrap inside the box. Water goes everywhere under a car.

He has to learn, sometime, to keep track of his keys.

Just use a heavier piece of wire and wire it up under the frame.

I have one on my Dodge. It's been there since 98 and I have used it about three times

Thanks for the input guys!

I used to hide a key in the rear brake light housing of my Jeep. Just needed a Phillips head if I ever needed it. Never falls out either

Epoxy is too brittle, I'd use 3m 5200. It's a polyurethane marine bedding compound. It'll keep stuff stuck and no problems with vibration or moisture.

I was told this from the locksmith that unlocked my truck:

Have a key made that won't start the vehicle, but will unlock the doors. Put the key behind your license plate. You can't see it, trust me. This way, all you need is a penny to back the screw out of the plate and you have a way to get into your car, but you can't start it. Just make sure your keys are actually in there or you won't be able to disable the alarm. Always put the key back when you remove it.

It's worked for me.

JB Weld is your friend.

Fine if you left your keys in your vehicle, but what happens when you take your keys with you and lose them?

the idea is to keep a key hidden somewhere inside the cab.

That is what I do. The 2nd set that starts the vehicle is hidden inside. The key hidden on the outside won't start the truck. Those are cheap to make and I have several for each vehicle.

Even if someone finds the outside key (highly unlikely), they can't start the truck unless they also find the interior key.

And it comes in a quick cure version.

Never thought of that. I never bragged about being the sharpest pencil in the pack.

Well, what type of adhesive do you suggest to glue the wallet to his ass?

I like the key pad on the door of my Ford. Almost never take the keys out of the rig.

Bolt one under the license plate. Most bolts are slotted and you can use a coin or pocket knife to get to it..use a stainless bolt or anti seize..just an idea....

tie wrap and duct tape

Sound advice from someone who lives and works in extreme weather extremes. I only buy 3M products when it comes to adhesives. They have some of the best chemical engineers in the world working for them. If you need things to stick, whether if be from tape to structural adhesive, don't buy anything other than 3M. Great products that work.

When you go to do this think about the first 3 places you try to put it. Dont put it there. The guy who said he had to get dirty to retrieve his has the idea.

I never take my key out, can't lose it if it there and I can break into the truck faster than unlocking it anyway.

Until your battery dies.....

The only downside is you darn well better not lose your knife, as you will have to cut the key out of the bedding compound.

I used to know a guy who always hid a key near his truck. He'd lay it on the ground by a log, put a piece of toilet paper over it, and covere it with some dirt, making sure the TP was sticking out. Nobody every bothered his key.

A couple years ago I was parking my 1986 Toyota 4Runner and when I got out and walked around behind the rig, one of those magnetic key holders fell to the ground. It had a key in it and I had no idea it was there because I didn't put it there.

If you wire tie a key somewhere, put a piece of rubber hose over the teeth to keep it clean.

Try some E-6000

How does this happen? The key is not in the ignition.

Magnetic has worked for me your years.
