I ordered this item as our previous lock had started to play up. It arrived very quickly and very well packed.

Instructions were very clear, and in a few minutes I had successfully removed the old lock and replaced it with the new one. Since the new lock has been fitted it has worked perfectly, without any problems or issues. It looks to be a very well designed and manufactured lock, and it feels as though it will give us better security than the lock that it replaced. All in all a very good value purchase and well worth the money paid for it.

Fitting the lock takes just a few minutes. The locks fitted easily into the doors and I've been very happy.

The only "learning curve" element with buying high security locks like this is to remember that your key goes in (and out) when the keyhole is in the horizontal position (90 degrees out from the traditional lock we've all grown up with). That takes a few days to sink in - lol.

I chose this CISA Astral S lock because I wanted a keyed pair for front and back doors. I needed the lock sizes to fit the doors and I also wanted the front lock in brass/goldish colour and the back in the steel/nickel colour.

Got this for a patio door that needed the shorter length lock. Fitting same as most Euro cylinders, just unscrew the bolt and slide out the old lock then slide in the new one. The new bolt was a bit long so used the old bolt as it was the same thread size. The lock seems solidly made. The Cisa keys are very secure with 10 pins in the side of the key. Have had no issues with inserting or turning them. As the keys are straight sided they are less likely to rip a hole in your trousers.

I've used these locks before on previous properties and have always been happy with them. I chose 2 barrels with 4 keyed-alike keys. All work perfectly and I'm happy with the increased security they provide.

After 1 month of use all is good.

I can't have a proper opinion after just a so short period.

However all went good with the order. It was quick and cheapest on the online market.

The product was easy to fit and seems like a good product based on my short experience plus the online reviews.

Similar to what other people mentioned:

Instructions were very clear, and in a few minutes I had successfully removed the old lock and replaced it with the new one. Since the new lock has been fitted it has worked perfectly, without any problems or issues. It looks to be a very well designed and manufactured lock, and it feels as though it will give us better security than the lock that it replaced. All in all a very good value purchase and well worth the money paid for it.

An excellent product - lock was replaced to allow access if keys had been left in the lock on the inside by the elderly homeowner who also found the lock much easier to lock and unlock than the previous lower-quality lock which was installed as standard. One happy customer, many thanks.

Very good product, quality, appearance, practicality.

I went for the internal knob and one-key solution.

I really can't understand why people keeps on having to use 5 different internal/external keys, one for each door., with the risk of being trapped in in case of emergency!

Safe adds security, practicality and elegance to your house!

We have had some problems in the past with a key being left inside the lock and being unable to open it from the outside. We were keen to avoid this in future so we looked for a replacement cylinder that would avoid this problem.

We also wanted a symmetrical key and this CISA Astral S cylinder provided the answer. So far so good and lives up to expectations. The other options we looked at didn't have a symmetrical key so not really suitable as we didn't want to be fumbling in the dark trying to get the key into the lock in the pouring rain.

The locks are extremely well build and have a lovely brushed finish to both the internal and extra sides.

The key is also very sturdy and Doesn’t feel like it will bend in anyway.

The little Allen key grub screw is a nice add on which allows you to remove the thumb turn and fit it to any door. I bought 2 barrels which were keyed alike and they both work perfectly.

Website is well designed and easy to navigate, customer service and dispatch time was spot on.

Will use this company again for any locks I need in the future.

This lock had exactly the features that I was after, and available in the range of sizes I needed to fit to all doors. The ability to open from one side when a key is in the other side of the lock has already avoided a potentially costly mistake.

The lock looks good, seems secure (who knows!?) and works fine. The only complication I had was that the screw to fit it seemed to be ridiculously long and couldn't be used with my door. I was able to reuse the screw from the previous lock though, so not a major problem.

Can two locks with different sizes have key-alike?

Providing the locks are of the same brand with the same number of pins, lock cylinders can be keyed alike despite the overall length being different.
