Very good lock- but beware cost of spare keys
Very good lock, installed very easily. Comes with 2 keys, but we need 4, and was very surprised when the 2 extra keys cost more than the lock itself ! In our local town, or online, the cost was about the same.

Great sturdy lock at a great price :)
Great study lock at a great price, was purchased for a bedroom door always known era to be of good quality and standing I myself installed the lock and being competent with my hands being a handy man I found the install straight forward and easy with fairly minimal tools (combi drill a rattler a sharp chisel couple of spade bits and the relevant marking implements a pencil tape square etc ) the lock looks tidy and smart and comes with a few spare keys 10/10 from me does the job and looks well hope this review helps :)

Will it replace the lock you have already?
I removed my existing ERA 5 lever deadbolt lock, which was getting sticky and unreliable after 20 years service. The ERA fortress lock was the closest match to what I already had. On the photos it looked exactly the same and the reported dimensions were the same, so I hoped it would be a like for like replacement. The product was delivered promptly and was much as expected, though a little vertical play on the bolt meant that the action can feel like it might snag a little. but overall no issues with what I have bought.What was really irritating was the minor dimensional differences to the existing one. The spacing between the two main fixiig holes was 2mm different. The the body is slightly thicker (less than 1 mm difference) and the brass plate that holds it in position was 0.2mm wider ( some chisel work needed there then). The key hole is positioned about 3 mm different to the original (aaagh!). The bolt moves out by a further couple of mm. Thus what could have been a 10 minuted swapover job now becomes more than an hour and needs chisel work and movement of holes.Irritating.Why could they not say it is not a like for like swapover? Why do they have to make these small dimensional changes?Whilst I had the old lock out I dismantled it, cleaned and lubricated it, so that it now works more smoothly than before. So I put it back ini position. The new lock can sit on the shelf for a bit longer, until I really have to change it and can face the task of making it fit properly.However, if you just want a lock to fit into a new door, it is fine. For my purpose, not so fine.
