Replacement of the turn signal switch - Peugeot 307 does not ignite

Hello this is my first post on an electrode so please be forgiving.
I am after changing the complex switch to a new one with the same serial number in Peugeot 307 from 2002. 1.4 I can't start the car, I suspect a problem with immo, can anyone advise.
My second question is how can I check if I have the remote control in the key or can I just open and close the car with the key, unfortunately I only have one key without the remote control - thank you for all the help.

Reg. 3.1.19. Do not send messages on archival subjects if this is another question, in particular other than the questioner. For the sake of respect to the questioner, create your own topic. You can only add a solution to the problem.

Maybe you haven't connected the plug from the loop on the ignition ... check if you have connected all the plugs, at least 4, if I remember correctly ...

thank you VERY tomorrow I check

The new switch is immo from another car.

Nonsense. there is only an antenna coil

Hi All - I solved the problem with my Peugeot, everything with the switch was ok (finally new, the same serial number etc.) during the car repair (then the mechanic replaced the switch for me) the mechanic noticed a leak around the engine, so he says we will wash the engine where - and washed - so washed that it flooded BSM and the car initially started firing so completely at all.
I read somewhere that you have to be careful not to flood this computer (you even have to watch out for rain ), well, a few bucks in the back, now after the exchange of just this BSM - I think - when I reach speed, until about 125-130 km / h, a sound signal is turned on, the same as I left the key in the ignition and door opening - I didn't have it before.

Thank you very much
