Dead Coin Battery
The most frequent reason why the 500 key fob won't function is the battery is dead. Modern key fobs only have only a limited range of operation and must be within a few inches of your vehicle in order to work. If you're not close to your vehicle, and you press the key fob button, the car won't respond, and will display an "Key Fob Not Detected" message in the instrument cluster.
If this happens then replace the battery for your coin-cell (Part Number CR2032) by a fresh one of a trusted brand like Panasonic Duracell or Energizer. You can find them at your local hardware store, or on the internet.

Water damage can happen in a variety of ways, from small splashes to submerging the fob into salt water at the beach. If you suspect that your fob has been exposed to water, put it in a dry rice bag to pull the moisture out. If this doesn't work, your fob is likely to need to be reprogrammed by a professional auto locksmith or dealer.
Water Damage

Saltwater can cause the circuit board to short, and eventually fail. If you get the fob wet, it's not an ideal choice but if you drop it in the water in a cup or forget to remove it from your pants pocket before running the washing machine and you don't have a chance, don't give in.
First remove the battery from the fob. Clean the electronic chip with isopropyl or a similar product and then dry it thoroughly before replacing the battery. Then test the fob to verify if it is working. If the key still doesn't function, it may need to be changed. This is typically done by a dealer or professional auto locksmith.

Receiver Module Issues

The remote usually has an operating range of 30 feet or less and if it's far from your vehicle, it will not respond to your commands. www.g28carkeys.co.uk can be solved by moving closer to your vehicle until it starts responding.

Interference

This could happen if the key fob is close to the radio transmitter (cell phones and radar detectors) or any other source of electromagnetic radiation. Other reasons the key fob may not function include a weak connection to the buttons, damage to the internal chip, or water damage.
If your key fob suddenly stopped working, or you've tried everything at home to fix it (e.g. replacing batteries, reprogramming or using the spare key fob, you could have a damaged receiver module on your 500. The receiver module is located under the dash and receives the radio frequency signals from the key fob. Then, it converts them into electronic commands that the vehicle interprets.
