Upvc front door?

It could simply be the handles, sometimes the spindles that are in the middle are supplied in two parts and occasionally snap. Take off the handles and insert a heavy screwdriver into the square hole and try to turn the latch back this way. If this works just buy a new set of handles at a B&Q. Take an old handle with you as there are a couple of sizes. I always try the cheapest option first but there is nothing wrong with the previous answer.
