hi

no  i am  not using  relays  this  is  not  the first  time  i  install remote  in this  kind  of  cars  and  i never  used  relays just  the ressistors  and i never  had  this  problem  before  

So, even when you disconnect  the lock wire of the alarm, and then touch the wire with the unlock value to ground it will unlock and then lock again?

Use relays and set up for negative trigger. Place a 4020 ohm resistor inline on the lock output, and a 665 ohm resistor inline on the unlock output. If you do not have a factory security system use a 1500 ohm for lock and a 250 ohm for unlock.
