Magnifying glass can be very useful.
The key turning in the lock is, alas, the result of wear & tear. I've switched the passenger and driver's door locks because of this.
S2 Switches are VERY delcate because they are surface mounted and do NOT have a supporting structure behind them to stop them comming away..
The reason for the switches breaking away is that us brits must be quite heavy fingered, and secondly, there is actually a delay from pressing the button and the car opening, so we tend to double press and press a bit harder. The silly thing here is PSA should of fitted an "Operating" lamp to the key like the S1 keys. But no. They decided not too.
Ive not actually come across a failed Texton box. However, it is hidden right up behind the dash glove box side. Ive never tried but will need to, but remove the glove box, watch out for the hidden screws behind the glove box mattings.. then you may also need to remove the upper air bag if fitted, this is an array of 8mm nuts on the under side. Disconnect the battery first to aloow a de-charge.. then up the back theres a stack of box's, the traffic master, the Texton box, and a smaller texton box stacked.. Its the larger one of the two. But as said, Ive not done this bit before, so no idea if they can be got at after the parts removed.
Are you certain the switch is soldered properly. The front two legs on the button side do nothing, just help mount it, its the rear two tiny pins that make the contact.
