Disassemble Antirobo del Ibiza 2000

Hello everyone, I am new in this forums and I don't know very well how to do it.
I need to disassemble the clauses of a Seat Ibiza of the year 2000. Since when the sun gives it and it warms up, it does not start, I know it is a contact problem inside but I have made contact cleaner of contacts and has not improved.

Many grace in advance

I would advise you to take it where a disarmed electric is not difficult but you must deceive the system so that it does not detect that it is bad but never a state and that is complicated, look inside the box exite some platinos that work like the relaxations if you manage to find the passage because they bridge it and now but better take it to an electric if you do not save electronics could get more expensive.

Thank you very much but what I need to get the Clauxor, is not an electronic breakdown but mechanical.
I know that in Opel with the key inside the Clauxor in position I with a small screwdriver by putting it through a hole all the hype comes out. But in the Ibiza I can't find anything similar
