They use cheap products that don't even last 6 months and they're overpriced (a dead bolt and knob for $200?).
Had someone come in on May 22nd, 2014 to replace a deadbolt and knob on a back entry. Pricing of the parts was $190 before tax. Now at Nov 20th, 2014 the door knob doesn't work. Their warranty is apparently only 3 months long and they won't sell me the part (Which is a Maxtech product that you can't even buy in Canada). Not sure if their operations are even legal as they don't have a proper address (just a PO box) and some 1-877 number that when googled goes to some locksmith company in Edmonton. They'll only send someone down to repair the doorknob (a job that will take less than 5mins) and charge me up the roof for a whole new assembly.
I only have seen one bad review of a company (the one and only review) that doesn't even have the same name but has the same PO box address... The name on the receipt i got was "RDL Services, Reliable Door and Lock Services" and the name on the Yellow Pages "Emergency Locksmith". I've filed a complaint with the BBB. Seems like sketchy business so avoid using them if you can.
