Dead Coin Battery

The most frequent reason that your 500 key fob won't function is an inactive battery. Modern key fobs offer an operating range that is limited and must be within only a few inches from the vehicle in order to work. If you are not within your car and hit the keyfob, it won't respond and display the message "Key Fob Not Detected".

Water Damage

Damage to the water supply can occur if you immerse the fob in the ocean, or wash it in a machine. Saltwater is particularly dangerous to the fob's circuit board, causing it to short out and eventually end up dying.
