Dead Key Fob Battery
Modern key fobs allow us to unlock doors, trunks and tailgates with ease without the need for a physical car key. Some key fobs have a built-in key that can be used to start cars. However, these devices are dependent on a small battery that powers their remote functions. If the battery is dead, the key fob cannot emit a signal that could be used to start the vehicle. There are a variety of ways to fix a dead key fob and get your car functioning again.
First, check if the key fob is actually dead. If it appears dead, you'll need to replace the batteries. You can do it yourself by removing the fob from its clip, or using a screwdriver with a flat head. You should not apply too much force or you may damage the fob. You should also make sure that you're using the correct kind of battery. Most key fobs are three-volt CR2032 batteries, however some models may require something different. You can find out what kind of battery your car requires in the owner's manual, or go to an Interstate All Battery Center and ask a specialist to assist you.
If the key fob isn't actually dead, you may be able to revive it by moving it closer to your car. The majority of key fobs utilize RFID (radio frequency identification), which only works at a short distance. The ignition system needs to be able to recognize the signal. You can unlock your car or even start it by moving a couple of inches closer.
Many automobile manufacturers have a backup system that can be activated if the battery of the key fob is low. For instance, the majority of Ford models have a separate slot for the key fob that will turn on the engine if it is properly inserted. You can find instructions in the owner's manual on how to locate the slot and insert the key fob correctly. If you're unable to get your car started by using this method, call roadside assistance.

Broken Key Loop
One of my MK5 keyfobs is broken off the small key loop at the top, where it connects 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 this.
I've also attempted to wrap the broken part of the ring using clear tape, but it didn't work as good. It's a shame, because I use the little split ring to keep my keys in place.
If the key fob's case is damaged, you could often open it up and replace the battery, if it isn't dead. There are online kits available for this, but they generally only offer temporary fixes - it might be better to take it to a mechanic who will replace the battery and reprogram the key fob. You may also find a replacement case at an home improvement store or a locksmith. They're not likely to be as expensive as the new key fob.
