I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
the cause is most likely the switch failing, as you suspected.
it could also be a problem with the lock/release mechanism itself, but more likely the switch.
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.

you can see if you can find one online or look for something similar from another manufacturer
the switch is just a switch, it needs to be tested for closing a circuit
