Locksmith in Markham, OntarioStraight talkabout what's on your door

Whatever the lock's own maker specifies, since cylinders differ: many call for a dry graphite or PTFE spray blown into the keyway and worked in with the key, once or twice a year, while others prohibit graphite and specify their own product instead. General-purpose oils, grease and sprays feel smooth at first but on most cylinders collect dust and clog the pins, which leads back to the sticking that breaks keys. A little goes a long way; too much of any lubricant can also hold moisture.

It asks; it does not compel. The stamp is a request that a key-cutting counter may or may not honour, and manufacturers say as much. Real control comes from a restricted keyway, whose blanks are issued only through authorised channels against a key card, or simply from knowing how many keys exist and who holds them. A rekey resets that count to a number you chose.

Yes. Bring the box, the template and the instructions, and tell the locksmith the model beforehand so the bore and backset can be checked against your door. If the kit turns out to need a larger hole or a different faceplate than the door has, the locksmith adapts the door or suggests a matching model. Hardware bought online sometimes arrives set for a different door thickness, which is a small adjustment on site.

A keypad or a lockbox with a rotating code works well there, since access can be shared without handing out a physical key that has to come back later. A weather-rated cylinder with a separate access key is another option if the property already runs on a keyed system. The locksmith can talk through how often the code should change and who on site should know it, so the gate stays convenient without staying open to everyone.

Yes, on both mechanical and electronic locks. A mechanical dial is reset to a new combination by working inside the lock body, while an electronic keypad is simply reprogrammed at the keypad or through its service menu. Changing it after a change in staff, a move, or simply out of caution is routine work rather than anything unusual, and it can be arranged as its own visit.
