My remote will lock the door but not open the doors. Why

2008 RDX - Keyless Entry Transmitter Test NOTE: If the doors unlock or lock with the transmitter, but the LED on the transmitter does not come on, the LED is faulty; replace the transmitter. If any door is open, you cannot lock the doors with the transmitter. Press the lock or unlock button five or six times to reset the transmitter. If the locks work, the transmitter is OK. If any of the transmitter buttons do not work, we can replace and reprogram a new one. Kindly call to schedule a appointment.
