What guarantee is there on locks?
As with any other consumer product warranties for locks vary. There are some common points to be aware of. Most warranties apply to workmanship and materials only, the manufacturer’s warranty does not cover installation and is usually voided if incorrectly fitted. (a locksmith’s personal guarantee covers correct installation) All warranties usually include a clause something like this “Polished Brass, antique bronze and similar plated finishes are classed as soft finishes, and as such cannot be warranted against deterioration or discolouration”. What this means is that these finishes are a thin plating which if scratched will allow the base metal to corrode. If a hardy finish is needed then stick with stainless steel treatments.
