In an emergency or out of hours situation, the prices will usually increase around 25 %.  British Standard locks will usually be dearer also.

It is very important that you have a secure home. Should you suspect that your current euro cylinders are outdated and vulnerable to attack, you should seriously consider replacing these locks with high security, 3 Star cylinders.
