Lost Keys
All keys should be kept safe at all times and no one should own more than one key at the same time (with the exception of broken keys in locks). Key Reports of stolen or lost keys are required to be completed and filed with University Safety. If the loss is deemed as a result of criminal crime, a police report must be filed. The replacement cost for a stolen or lost lock key is $30 per key. The fee must be paid to the responsible owner of the key.

Broken Keys
It's not unusual for keys to break after just a few years. If the key breaks inside the lock, you will have to replace it. But if the rest of the key is still in good condition you may be able to fix it.
A paperclip can be used to grab the broken piece from both sides and lever it out. If it isn't stuck far within the lock, you can also try using an plier. If the key is broken close to the the lock, you may require a "key extraction" tool with an elongated bar with an elongated barb that is similar to the screw. The bar is put into the locking mechanism, and then twisted until it digs the barb into it. This will release the key.
If you have the right tools, it's difficult to replace the keyboard key. You'll require keys, a cap (the plastic piece that sits over the switch) along with a keypad, and a key retainer clip. Key caps have small plastic or metal posts that are located on the underside and fit into tiny slots on the switch. To replace a key cap, carefully remove the internal parts of the key and record their position so that you can replace them later. It is possible to clean the keyboard with rubbing alcohol before moving on.
Fobs Not Working
It may appear impossible that your key fob requires regular maintenance, but it's true that they can be out of commission at any time. In some cases it's a simple one such as dead batteries. If you have changed your batteries but your fob is still not working, you should look for a different solution.
Another reason that can cause a fob to stop working is because the buttons have worn out. When you press the button on your fob the contacts send coded messages to the receiver in your car, which communicates the action you would like the key to perform. If these contacts are damaged and the button is not working, it may not work at all or it may send different messages than what you wanted to.
One solution to this problem is to use a physical key to unlock your car's doors or start the engine. G28 can reset the fob following the instructions in the owner's handbook of your car (check online for specific instructions).
If replacing the batteries and reprogramming your key fob isn't working, you might need to have it replaced or repaired. Modern keys must be programmed to be compatible with your vehicle's specific VIN and some errors or wear and tear could cause the programming to become corrupted.
Transponder Chips
The transponder chip in your car keys is a very important component of the key. They transmit a signal with a unique frequency when the key is placed in the ignition. The car's device recognizes the number and is sure it's you. The engine won't start in the event that the device inside the car isn't able to recognize the signal. This is a measure of security designed to stop thieves from hot wiring their vehicles and stealing them.
The chip is not powered by a battery. Therefore, it does not require replacement or charging. It needs to be programmed by someone who has access to the ECU of your car. This is why you need to make sure you take your keys to a professional locksmith.
Transponder chips are available in various varieties that are widely used, but the most commonly used are Rolling Code and Crypto. Key blanks feature heads made of plastic that have a slot that accommodates the glass transponder or ampoule, it is then inserted into a carrier (or sleeves) on the back of the bow (plastic head). Here is a photo of one of these sleeve holders from an Ford key here. You can take the transponder from a damaged key by using an PVC ratcheting pipe cutter or a different method to remove the sleeve.
A regular transponder key is more expensive than a regular metal key due to the chip, however, it is cheaper than a fob or smart key. The price of these keys will depend on the model and make of your vehicle.
