Without taking this topic completely off of the original topic on Rear View Cameras, I will fill in you guy's in on how I get around the issue of storing my Key Fob when participating in Surfing ( I didn't write 'Water Sports' as some may see inuendo). Presently with my Honda I have 3 key Fobs. One is the original everyday key on my keyring which I use to drive. The other two are spares. One is a fully functional Spare and the other is a Blank Key Blade without the Fob remote being paired or activated. When I go Surfing I will leave the original Key in the Car and lock the door with the Non-Activiated Spare Key. I will then place this key in a 100% waterproof diving bag and key this tethered in the Key Pocket of my Wetsuit. To ensure the Key is completely protected in the Diving Bag I put the Key inside a Balloon, this protects the key should the Diving Bag ever leak, this part is just satisfy my paranoia.
Once I have finished Surfing I will get the Spare key out of the Diving Bag and unlock the Door with the Blade. With my current car this will then almost definitely set off the alarm, which I then have to deactivate with my Original Key stored in the car.
My dilemma with the GTI is I could continue to unlock the car the same way, but the Key hole is covered with a cap which will eventually result the paint work being damaged at some point.
I am planning on having a third key produced for my GTI which will a fully operational Remote Locking Fob. I have tested placing the Remote Locking key Fob for my Honda in the Diving Bag and submerging it in cold water for a long period of time. It does still work after and remains bone dry. I plan on leaving the original key on my keyring which I use for driving as usual in the car and taking the spare in the water (within the Diving Bag). Should anything happen to the Key I will have another spare at home which can be obtained to access the car, rather than breaking in and damaging it.
I can guarantee Diving Bags work, I have used it for years and I even know surfers who take their MP3 Players and iPhones in with them. Sounds ridiculous but true

Anyway back on to topic now. I am happy to have configured my Car with the Rear View Camera. It may be viewed as a bit of a gimmick by some, but why not make the most of your car if you can afford it.
