I purchased a cylinder on April 4th of this year and replaced an old one. However, I recently lost a key, so I replaced the cylinder again. The cylinder I removed is in good condition and fully functional, so I am offering it for sale. That being said, it has been used for three months. The exterior door is sheltered by an eaves, so it is not exposed to direct rain except during storms. The four keys have no noticeable scratches, but there is some discoloration and small, inconspicuous scratches where they are touched. Also, there is a small scratch on the key insertion slot of the upper cylinder. Please consider this item as used and understand its condition before purchasing. A copy of the replacement instructions will be included.
