Dead Key Fob Battery
Modern key fobs allow us to open trunks, doors and tailgates without having fumble around for a key. Some key fobs even have an inbuilt key that can be used to start cars. The fobs are powered by a tiny battery. If the battery is dead, then the key fob cannot transmit the signal needed to turn on the vehicle. There are several methods to fix a dead car key fob.
First, check if the key fob is actually dead. If it appears to be, you'll need to replace the battery. You can do it yourself by taking the fob off its clip, or using an screwdriver with a flat-head. You should not apply too much force or you may damage the fob. It's also important to make sure you're replacing the correct battery type. Some models might require a different type of battery. If you aren't sure what type your car requires it is possible to find the information in the owner's manual or visit an Interstate All Battery Center to have a battery expert help you.
If the key fob isn't actually dead, you may be able to revive it by moving closer to your vehicle. The majority of key fobs utilize RFID (radio frequency identification) that only operates in a limited distance. The ignition system has to be able detect the signal. You can unlock your vehicle or even start it by moving a few inches nearer.
Many car manufacturers have backup mechanisms that can be activated when the battery for the key fob is dead. For example, most Ford models have a separate slot for the key fob which will start the engine when it is properly inserted. Go through the owner's manual to find information on where to find the slot and how to insert the key fob. If you're unable to start your car with this method, make sure to get assistance from roadside assistance.
Broken Key Ring
The internal chip of the key fob communicates to your car's immobilizer to enable the motor. This chip can be damaged or there may be programming mistakes. If this happens, your key fob won't be able to send the correct identification code, and your car won't start. A faulty transponder can be caused by physical damage to the key shell, or wear and tear on the contact pads.
Often when car key repair service begins to have trouble communicating with the immobilizer system of your vehicle and you notice specific warning indicators on your dashboard. These include warnings about errors flashing lights, or the key is not locking the vehicle. If you see these warnings, contact your local locksmith immediately for a replacement key fob or repair.
It's easy to damage your key ring when you put too much pressure on it, especially when carrying many keys. This could cause the fob to split in half. This is one of the main reasons for a broken car key. If this happens, you can try to use super glue to fix the issue by applying a small amount the glue on both sides of the crack and pressing them in a controlled manner. Use a gel-type of glue that drys slowly to prevent drips or runniness.

Broken Key Loop
One of my MK5 keyfobs has snapped off the little key ring loop at the top where it attaches to the keyfob. It's made of plastic or soft metal. I've punched a hole and then wet-sanded the area to strengthen it, but I suspect that the issue isn't solved by that.
I've also wrapped the broken portion of the ring in clear tape, but that doesn't seem to do much good. It's a shame because I rely on the small split ring to keep my keys in the right place.
If the key fob's case is damaged It's usually possible to remove the case and replace the battery (assuming the battery isn't already dead). There are kits online to help, but they generally only offer temporary fixes - it may be faster to take it to a mechanic who will replace the battery and reprogram the key fob. You can also locate the new case at an a locksmith or home improvement stores. They are not likely to be as costly as a new key fob.
