Wayne Winton Locksmith and safe technician comments on the difference between Electronic safe locks and mechanical gun safe locks.

I highly recommend hiring a qualified, competent safe technician to change out and swap the electronic lock out for the mechanical lock and set the code for you. Much like you would hire an ASE certified mechanic to work on your vehicle, a good safe technician or locksmith can save you locking yourself out of your own safe!

Warning ⚠️ Most of the safes I open are because someone wanted to DIY and missed an important step. find a safe technician here:
