Sometimes extreme cold or heat can cause the car key to stop functioning properly. It is best to wait a few minutes before replacing it.
It's a major pain when the keys to your car fail and they happen at the most difficult times! Repairing a damaged key without the need to purchase another one.
Dead Key Fob Batteries
Modern key fobs allow us to open trunks, doors, and tailgates with ease without the need to search for a physical car key. Some key fobs even come with a built-in key that can be used to start our vehicles. These fobs are powered by a small battery. If the battery fails, the key fob cannot transmit a signal that can activate the vehicle. There are several ways to fix a dead car key fob.
First, try to determine if your key fob is in fact dead. If it seems to be, then you'll need to replace the battery. You can do this yourself by removing the key fob from its clip or using a small flat head screwdriver to remove it. Do not apply automotive key repair or it could cause damage to the fob. You should also make sure that you're using the correct kind of battery. The majority of key fobs utilize CR2032 3-Volt batteries, but certain models may require something different. You can find out what kind of battery your vehicle requires by consulting the owner's manual, or go to an Interstate All Battery Center and have a battery specialist help you.
You can sometimes revive a key fob that isn't dead by moving closer to the car. Most key fobs use RFID (radio frequency identification) that only operates in a limited range. The ignition system has to be able to recognize the signal. You can unlock your car or even start it if you move few inches closer.
Many car manufacturers include a backup mechanism that can be triggered when the key fob battery is dead. For instance, the majority of Ford models have a separate slot for the key fob that will activate the engine when inserted correctly. You can find the instructions in the owner's manual of how to locate the slot and insert the key fob in the correct way. If you're unable to get your car started by using this method, call roadside assistance.
Broken Key Ring
The internal chip inside the key fob communicates to the immobilizer of your car to enable the motor. The chip could be damaged or there might be programming mistakes. If this occurs the key fob won't be able to transmit the correct identification code, and your car won't start. A damaged transponder may be caused by physical damage to the key shell, or wear and tear on the contact pads.
You will often see warning signs on your dashboard if a keyfob has trouble communicating with the immobilizer system of your vehicle. These can include error messages, a flashing light or the key not locking or unlocking the vehicle. If you notice these warnings contact your local locksmith immediately for key fob replacement or repair.
If you carry a lot of keys, it's easy to scratch the key ring. This could cause the fob to split in half. This is one of the main reasons for a broken car keys. If this happens, you can try to use super glue to repair it by applying a small amount the glue on both sides of the split and carefully pressing them together. Make use of a gel-type glue that dries slowly to prevent drips or runniness.
If this method doesn't work then you must seek out a professional locksmith as soon as possible in order to avoid further damage to your vehicle. A professional locksmith will be able to replace or repair your key fob quickly and will be able to ensure that the ignition lock as well as the door lock do not get damaged in the process.

Broken Key Loop
One of my MK5 keysfobs snapped off the small key ring that is at the top, where it attaches the keyfob. It appears to be made of extremely soft plastic or metal. I've drilled a hole, and wet-sanded it to strengthen it, but I suspect the problem isn't resolved by this.
I've also wrapped the broken part of the ring in clear tape, but that does not seem to do any good. It's really too bad as I use the rings to keep my keys in place on the little mini-split ring that holds the larger split ring for the other keyfobs.
If the key fob's case is broken, you can often remove it and replace the battery if it isn't already dead. There are online kits for this, however they generally only offer an interim fix. It may be faster to take it to a mechanic who will replace the battery and reprogram the key fob. Alternatively, you might be able to find an alternative case at the home improvement store or locksmith. These cases aren't as expensive as the new key fob.
