Two channels doing two different jobs. The phone takes anything already happening, at any hour. The form takes the work that improves with a day of notice, because a written description can be priced, parts-checked and scheduled before anyone drives anywhere.
Three details turn a message into a price rather than a follow-up question: the address with its unit number, how many cylinders the job covers, and the brand cast into the lock face. Schlage, Weiser, Kwikset, Weslock and Arrow all turn up in Burnaby, and they do not take the same parts.
Home, vehicle and commercial work all run off the same number. If you are not certain which heading your job belongs under, pick the closest one and describe it in the message instead.
Every name below opens a page of its own. Start with the one your address sits in, then bring whatever it does not answer to the form above.
