The most frequent reason why your 500 key fob won't work is a dead battery. Key fobs of today have an operating range that is limited and must be within a few inches of the vehicle to work.

Water damage can happen in a number of ways, ranging from a light splash to submerging the fob salt water at the beach. If you suspect your fob has been exposed to water, try placing it in a dry rice bag to pull the moisture out. If this doesn't work your fob will probably need to be reprogrammed by an experienced auto locksmith or by the dealer.


Water Damage

Water damage can occur when you immerse the fob in the ocean, or wash it in a washer. Saltwater can cause the circuit board to short, and eventually die. It's not good to get the fob wet however, don't give it up even if you accidentally drop the fob in water, or fail to remove it from your pants pocket.

First, remove the battery from the fob. Before replacing the battery clean the electronic chip using isopropyl or similar products. Check fiat punto keys to determine if it's functioning. If the key isn't working it could need to be programmed again. This is usually done by an auto locksmith or dealer.

The locksmith will need to cut the key to match the ignition on your vehicle. The locksmith also needs to reprogram your fob in the vehicle's system.

Receiver Module Issues

The 500 key fob could be inoperable because it's out of range. 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. This can easily be resolved by moving it closer to your vehicle until it begins responding.

If your fob doesn't work after you replace the battery for the coin, also called a "button", "watch" or "button" or "button", it may be due to a malfunction on the internal circuit board. In most cases, reprogramming the fob will resolve this issue. You can find the instructions for most vehicles on YouTube or in the owner's manual.

Interference

This could happen if the key fob is close to an electronic radio transmitter (cell phones and radar detectors) or any other source of electromagnetic radiation. Other reasons the key fob may not function include a poor connection to the buttons and internal chip or water damage.

If the key fob suddenly stopped working, without notice or after trying everything you can do at home to resolve it e.g. You might have a damaged 500 receiver module in the event that you've tried replacing the battery, reprogramming, and using an alternative key fob. The receiver module is situated under the dash and is able to pick up the radio frequency signals from the key fob. It converts them into electronic commands that the vehicle interprets.

Luckily, there is an easy method to reset every single system on board in your 500 device, including the key fob. Disconnect the battery for 15 minutes by taking off first the negative cable, then the positive cable. Reconnect the battery.
