Master Lock MAS291 – Frequently Asked Questions

1) What does the Master Lock 291 rekeying kit actually contain?
The No. 291 kit is a pin tumbler service assortment: the most frequently used pin tumbler components, packed in a case with deep storage compartments and a sealing cover that keeps the pins from migrating between compartments. A reference chart comes attached to the cover so you are not hunting for pin sizes on the bench. It is a service kit, not a lock, so there is nothing here that mounts to a door.
2) Will the Master Lock 291 kit rekey my Master Lock padlocks?
It is built for Master Lock Pro Series and commercial security rekeyable padlocks. If the padlock is a rekeyable Master Lock in one of those lines, the 291 carries the pin tumbler components to service it. A padlock that is not rekeyable has no cylinder you can pin, so the kit does nothing for it, and the kit is not sold as a rekeying set for other manufacturers' cylinders.
3) Can I use the Master Lock 291 pinning kit to rekey door locks and deadbolts?
No. The 291 is scoped to Master Lock Pro Series and commercial security rekeyable padlocks. Door cylinders use different pin lengths and keyways, so a locksmith rekeying knobs, levers, or deadbolts wants a general pin kit sized to those cylinders instead. Use the 291 for padlock service work.
4) Do I have to buy a whole new Master Lock 291 kit when I run out of one pin size?
No. Rekeying part refills can be ordered separately, so when you burn through a particular pin size, you replace that component rather than the case. For a property manager or a locksmith rekeying a batch of padlocks at turnover, that keeps the same case in service and the reference chart on the cover stays with it.
5) Is the Master Lock 291 rekeying kit a complete padlock or just the service parts?
Just the service parts. The 291 is a pin type rekeying kit, an assortment of pin tumbler service components in a compartment case with a reference chart. Keys, key blanks, and the padlocks themselves are separate purchases, and you need your own pinning tools to do the work.
6) How do I order the Master Lock pinning kit, and is there more than one version?
There is one configuration: Master Lock 291, ordered as model MAS291. No size, finish, or capacity choice to make, so a distributor or MRO buyer setting up a stock line only carries the single item.
7) Is the Master Lock 291 kit meant for a maintenance shop or for occasional home use?
Master Lock classes the 291 as a residential grade item, but the components it carries are for Pro Series and commercial security rekeyable padlocks. In practice it suits a maintenance shop or a locksmith who services those padlocks in volume; a buyer with two padlocks to rekey gets more use out of ordering the specific pins than a full assortment.
