A colleague checked all my fuses on my peugeot 206

a colleague checked all my fuses on my peugeot 206 - 02 reg. This involved taking them all out one by one and checking them - This was due to a headlight problem - The headlights have now been replaced and work. However, since he has done this my keb fob does not work and there is no physical way of locking the car boot - I rang peugeot and they are looking to charge me £75 to re-set my fob. What do you think caused the fob to break and is there anyway to reolve this issue without having the key fob re-set?
