How do i reset a master lock 1500i closed? - Locks & Locksmithing

There is no way to reset a combo on a locked lock.
the only way to get the combo is to progress the numbers starting from 0000 and then 0001,0002,0003 etc.. all the way through until you get the lock to open. it will help if you know at least the first two numbers --- like if you set it to a date of year say ( birthday etc.. ) --so you will know that starting with 1900,1901,1902,1903 and so on and so on. I am a locksmith and when we get these locks in the shop from customers, we treat them like a puzzle and run through the combo in our spare time. ( the quickest time I have had on a 4 digit combo is 25 minutes -- the longest I have spent on a 4 digit lock is 2 days ).. progression is the only way for you to figure out the combo. some wheels can be read by a locksmith using special tools and you can check with your local lockshop and see if they have these readers, but I have never had luck reading the master pad locks.
just do it in your spare time or when you are watching tv -- you will get it eventually.
