Do we need to lubricate our cars keyholes such as the ignition, boot and doors?
Reason I asked is because recently, I was locked out of my home because my door lock keyhole was spoiled due to lack of lubricate after 2 years. (the spring got jammed with dust, grime and what not.) Had to call the locksmith to break in (normal lockpicking can't work, have to destroy and replace a new one) The lock smith explained it happened because I didn't lubricate it.
