ISEO 5 Pin F5 Euro Thumb-turn cylinders

This is the most important point to get right so you don't leave your home vulnerable to attack. The best way to get the correct size is to remove the cylinder from the door. (see the help page for instructions to do this). Once you have the cylinder out the door you need to measure from one side of the cylinder to the center of the fixing screw hole and then the same from the other side. Make a note of which is the inside measurement and which is the outside. Once you have this you need to match the size to the sizes available online. You want to get this as exact as possible. The cylinder sizes go up in increments of 5mm.

Yes this is possible. We offer the ABUS Pfaffenhain range of padlocks and also we can purchase Euro Cylinder to a Kitemarked level and Rim cylinders which can all be keyed alike or Masterkeyed.

Yes, this is called keyed alike. We build the cylinders for you to match 1 x set of keys. Please note you will only get 1 x set of keys with however many cylinders you order. So if you order 5 x Cylinders keyed alike you will only get 1 x set of keys. We can make you additional keys to match the cylinder at the same time.

The cylinders we can offer have different features, some are low basic security for internal doors to student bedrooms and others are for external doors which need to be more secure with all the high security features. The amount of pins is a good indication of security. 5 pins are the basic and 6 pins is better. The best external cylinders are kitemarked cylinders, the ABS or KABA GEGE 3 star are the top level and then we have an ABUS 1 star kitemarked cylinder with our restricted key section. Most insurance companies will now require you to have a kitemarked cylinder on the UPVC or Composite doors to give the best security.

It depends on what suits you, however, there are situations where one would be better suited for the job.

If you are using the lock on a house of multiple occupancy, you would need access for fire safety, therefore a Thumbturn would need to be fitted.

You can still fit the euro double cylinder, but it's always a good idea to keep your keys in a safe place where every member of the household knows where they are.

No unfortunately not, the cylinders internals need to be changed to operate with a thumbturn so you have to replace your lock with a new cylinder. Sometimes we can offer you the same key as you already have on the new cylinder but only if its a brand we stock and can assemble for you.
