Lost Keys
All keys must be kept secure at all at all times. There is no way to have more than one at a time (except for keys that have been damaged in locks). Key reports that are missing or stolen must be submitted to University Safety. If the loss is deemed to be the result of criminal or other criminal activity, a police investigation must also be filed.

Broken Keys
After a couple of years of use, it's not uncommon for keys to break. If your key breaks inside the lock, you will need to replace it. If the remainder of the lock key is still in good shape you might be able to fix it.
A paperclip can be used to grab the broken piece from both sides and lever it out. If the broken piece isn't stuck too far within the lock, you can use pliers. If the key is damaged close to the lock, you may need an "key extraction" tool that has a bar that has barbs that resemble a screw. The bar can be placed inside the lock and by twisting it, you can pierce the barb into the key to pull it out.
If you have the right tools, it's difficult to replace the keyboard key. You'll require the key cap (the piece of plastic that covers the switch) along with a key pad as well as a key retainer clip. Key caps are made of either metal or plastic posts which are inserted into slots on the switch.

Fobs Not Working
It may seem odd to imagine that your key fob may require regular maintenance but it's not unusual for them to cease working at some time. In some cases, the problem is a simple one that is caused by dead batteries. If you've replaced your batteries and your fob still doesn't work, it may be an opportunity to try something else.

Another reason that causes fobs to cease functioning is that the buttons are been worn out. When you press a button on your fob the contacts inside send signals to the receiver in your vehicle that indicate the actions you would like the key to complete. If the contacts on your key fob are worn out they may not be able to press the button, or it may send a different signal than what you intended.
A possible quick fix for this issue is to use a physical key to unlock your car's doors and start the engine. You can reset the fob by following the procedure in your vehicle's owner's manual (check online for instructions for your specific model).
If replacing the batteries or reprogramming doesn't work, it may be necessary to replace or repair your key fob. Modern keys need to be programmed to match your vehicle's specific Vehicle Identification Number and some errors or wear and tear can cause this programming to become corrupted.
Transponder Chips
The transponder chips on your car key are a very crucial component of your car key. They send out an electronic signal with a specific frequency when the key is inserted in the ignition. The car's device recognizes the code and can tell it's you. The engine won't begin to run in the event that the device inside the car doesn't recognize the signal. This is a security feature designed to prevent thieves from hot wiring their vehicles and driving them away.
