how do I pressurise my worcester 25si?

i have seen the answer relating to using the key underneath the unit, but i cannot find this on my boiler. Am i being really stupid or could it be somewhere else than underneath?

hi deano
the boiler has no key and no bottom plate. Is it possible there is another way to do it?

there is a panel what clips underneath the boiler.the key should be clipped to it.
