Extreme heat or cold can sometimes cause a vehicle to stop working. Take a moment before replacing it.
When your car keys break it's a huge hassle. It occurs at the most inconvenient timing! You can repair a broken key without needing to purchase another one.
Dead Key Fob Battery
Modern key fobs let us unlock doors, trunks and tailgates without the need for a physical car key. Some key fobs have an inbuilt key that can be used to start our vehicles. These key fobs are powered by a tiny battery. If the battery is dead, then the key fob will not be able to transmit the signal to activate the vehicle. There are a variety of methods to fix a dead vehicle key fob.
First, you must determine if the key fob is really dead. If it appears to be, then you'll need to replace the battery. You can do this yourself by removing the fob from its clip, or by using an screwdriver with a flat-head. Be careful not to put too much pressure on the fob or you could end up damaging the fob. It's also important to be sure you're replacing the correct type of battery. Most key fobs use the CR2032 3-Volt battery, however certain models may require a different type of battery. You can determine what type of battery your car requires by consulting the owner's manual, or you can go to an Interstate All Battery Center and ask a specialist to assist you.
If the key fob actually isn't dead, you can sometimes revive it by bringing it closer to your car. Most key fobs use RFID (radio frequency identification) that only operates within a narrow range. The ignition system has to be able to recognize the signal. If you can move just a few inches closer to your car, it might unlock or even start it.
Many car manufacturers include backup mechanisms that can be triggered when the battery for the key fob is dead. For example, most Ford models have a separate slot for the key fob which will turn on the engine if properly inserted. Go through the owner's manual to find details on how to locate the slot and how to insert the key fob. If you are unable to get your car started using this method, contact roadside assistance.
Broken Key Ring
The key fob's internal chip is the one that communicates with your vehicle's immobilizer system to begin the engine. If the chip is damaged or if there are programming errors, the key will not be able transmit the correct identification code and your car won't start. In some cases a malfunctioning transponder key may also be caused by physical damage or wear and tear to the key shell or contact pads.
Often, when a key fob begins to fail to communicate with your vehicle's immobilizer system and you notice specific warning signs on the dashboard. These include error messages flashing lights, or the key not locking the vehicle. If you are noticing these warnings contact your local locksmith immediately for a replacement key fob or repair.

Broken Key Loop
One of my MK5 keysfobs snapped off the tiny key ring at the top, which is where it joins the keyfob. It's believed to be made of very soft metal or plastic. I've drilled the hole and wet-sanded it to make it more durable. However, I'm sure that's not helping.
I've also wrapped the broken portion of the ring with clear tape, but it doesn't seem to do much good. It's really too bad, since I use the tiny ring to hold my keys in place on the tiny mini-splitring that holds the bigger split ring for the keyfobs that I have.
If car key fob repairs is broken It's usually possible to remove the case and replace the battery (assuming the battery isn't already dead). Online kits are available, but they only provide a temporary solution. It may be quicker to get it fixed by a professional. You can also find a new case at the locksmith or home improvement store. They're unlikely to be as expensive as a new key fob.
