How to enter imperial lab in reandore quest

Hi,

I am in reandore, I got a key from a scientific to enter the lab (after a boring quest on a planet full off spiders), I am able to enter the first perimeter but then there is a kind of magneti wall that block me the entrance of the second perimeter.

I tried to find an other way but soldiers attack me (whereas I am working for them) and even by tryig to rush it doen't lead me to the lab entance.

Is there something special to do or I got a bug quest.

I wanted to kill everybody by using a mecha but I have no side quest that allows me to drive a mecha and I have to low pick skill to steal one…

thanks in advance,
