The short answer: As with most things Duct Tape will fix a broken access control key fob. That is assuming the reader still reads the electronics inside.
Once a fob or access card stops working it is possible that the microchip inside is damaged. A prox card is made up of a coil of wire that works like an antenna, and a microchip. The card holds a code number that a reader can extract.
If that number is programmed to allow access to the door the door will unlock when the card is presented.
The long answer is that if the card number has not been programmed into the system the door will not unlock. The card (or fob) will not work no matter how much duct tape or WD40 you use.

I have a Toyota, and my key fob light stayed on also. I called the dealer, and they said the button on the fob was stuck down INSIDE the fob. So, I simply unscrewed the screw on the back of the fob, opened the fob, then put it back together. The fob was fixed. I didn't have to fix anything in the fob.
Two wire connection in the fob. Open and check both wires are fix in place.

This happened to my with my Explorer. The key fob was squished and the panic button was being hit when I locked the doors. First try a different key fob. If that works or if you don't have one pull the key fob apart and make sure the contacts aren't touching. Good Luck.
To fix the locking part of the key pivot feature on a Volvo S60, first, inspect the key fob for any visible damage or debris. If the key pivot is stuck or not functioning smoothly, try cleaning it with a soft cloth and some isopropyl alcohol. If the issue persists, consider replacing the key fob battery or consulting a professional locksmith or Volvo dealership for further assistance. In some cases, the entire key fob may need to be replaced if internal mechanisms are damaged.
