Have an s60 2.4t. Very nice car except the remotes are problematic. When you take delivery on your car, make sure dealer goes through the whole locking..arming..unlocking shtick in detail. The 2 remotes I have are malfunctioning and I am getting alarms at 2am...Brought to dealer and they said they could not find anything wrong. I surfed for an answer and found other owners with similar probs. It seems that the remotes are poor design and the panic button (red) sticks in the remote. Since there is no l.e.d. to let you know this, it sets of the alarm, and you can't shut it off because the button is stuck. You have to use your keys on the door. What a nitemare! My dealer said Volvo Tech HQ in Jersey is aware of the problems with remotes/door locks/alarm, but I have had no fix yet. I have seen on the net where dealers are putting o-rings inside the remote case to disable the panic buttons. All this leading edge technology...spoiled by bad design in the remote fobs. I have backed off the screw a couple turns so the damn panic button works freely but the design is faulty. If you screw it down tight and water resistant...that panic button is going to hang up and make your life miserable! Dealer said no way to program out the panic mode...
