I asked a customer to email me photos of the locks on a house that he had recently purchased. I had previously met him when I installed a Mul-t-lock Hercular deadbolt at his former residence. He expressed an interest in installing similar locks at his new home. After viewing his photos I suggested that I could retrofit his locks with Mul-t-lock cylinders. I would match the finish (colour) of the hardware and for convenience all of the locks would operate with the same key.
Mul-t-lock manufactures high security cylinders to retrofit many brands of residential and commercial door hardware.
