Can one key from laptop keyboard be replaced ?

The letter k on my laptop has become detached. I can type with it set in it's place, but it wobbles. It is a three year old Toshiba Satellite A 215 S4697 Part # PSAEGU -oovoou. I cannot seem to find the particular laptop on line. Micro Center says this keyboard needs to be replaced ? Three year old laptop. Is there an adhesive or special glue for JUST REATTACHING the key ? I cannot seem to allign the k with the slots it should go in.
