Keyless entry is a fancy option T3's don't have (until 2014 I believe)

Because we're talking about the keys, I was utterly confused watching this video.

Actually I have a "black and silver" VW badge type key, but the logo itself is blue? (Spare key badge looks brand new).

 

it's relatively thin. Slide that thing into your wallet. It'd make the grown up equivalent of a high school condom ring imprint. \\/

Wallet may be easily left inside alike. Neck chain pendant is more reliable solution.

 

Embarrased to say, but the same scenario with the key in the cargo area. AAA used the airbag method and failed. Unfortunately, the spare key was in NC, and I was in MD. I wanted to break a window, but the wife wouldn't have it. "You are NOT going to break a window on my car"![-X Instead, she flew to NC, rented a car to get home, and returned the next day.#-o$$$$$$

 

Maybe store the key, without the FOB, in a Hideaway... that way, you can always get in to fetch your keyfob you locked in.

A How To.

 

After jumping off my boat with my keys in pocket, and 125 miles from the nearest dealer. I now keep a key with the battery removed in one of those magnetic boxes (materlock brand) duct taped under the hood.

 

After jumping off my boat with my keys in pocket

Once upon a time it happened to me too. I was so very long time waiting for a wind that having arrived to the spot jumped into the water absent-minded.

Don't forget on a 7P ("T3") with KESSY, you have both active and passive action in the fob, so to leave a spare fob in/on the vehicle, not only must the battery (active transmitter) be removed, the fob itself must be completely RF shielded (passive transponder) to prevent the vehicle from "seeing" it and preventing the vehicle from being fully locked, secured and alarmed.
A bit of planning with regards to the hiding of the separate components prevents all the rock, and/or dealer and tow truck delay issues!
It works.

 

My biggest fear is having that keyfob in my pocket and slipping and going into the drink while wading in a river fly fishing. Have a solution for it, though, now, after seeing this thread.

 

That was my big worry too!
As far as it goes, double wrapping the batteryless KESSY fob with two of those embedded chip type credit card security envelopes ( slide one on from either end) seems to shield the transponder more than adequately, and is cheap.

 

I always assumed the battery in the fob was for locking and unlocking the doors remotely. I took a swim with my 2004 Golf GTI fob years ago and I only lost the lock/unlock function. The key still opened the doors and started the car.

I think you are correct. IIRC there is an RFID chip inside the MKIV key fob that communicates with the IMMO chip/system in the ECU and is powered by EMF, not the battery.

Goes to show that water isn't going to necessarily kill your electronics. A friend of mine once sent her iPhone through the washing machine. She put it in a bag of rice for a week or so (to pull moisture away) and the darn thing still works...screen and everything.

If you jump into the water with the key fob in your pocket, you may or may not be screwed. Best to at least break the key down into all the little pieces that it's made of and let the electronics dry out. Better if you had some 99% iso or other inert liquid to clean off all the impurities from the water soak (you can even try immersing the circuit board in the iso for a few minutes to clean it). You may need to replace the battery. If that doesn't work, well, then you are screwed...

It sure would be nice if the RFID chip were in a water protected area of the key fob. That way you could at least manually unlock your vehicle with the plastic emergency key and still start even if you do submerge your key fob...which in Perry01's case is exactly what happened. It's a healthy fear y'all have, but water submersion isn't ASSURED destruction.

 

I just removed the battery from my key fob and the truck started.

Cool...nice bit of info Perry01

I don't want to be the one to test this out, but I'd say you have an outside to moderate chance of NOT getting stranded should you jump in the water with your key...just hope you remember earlier than later.

 

Yea, I was pretty sure the battery in the fob is used to remotely lock/unlock the vehicle.

After my water excursion, the car would not start. MFD said immobilizer active. Key got stuck in the ignition. Basically no way to start the car unless I had another key.

 

Then carry a spare, deactivated, in the car, just in case it's not fresh water, your fob gets broken, or lost, the dog decides to chew it, the sprog decides to take it out of your coat pocket/purse and lob it at a passing car......

 

Read above, I do. And this was fresh water. Lake Roosevelt in Arizona to be exact.
