Hello Haq!
Could it be the key just needs re-coding? maybe you are worrying to much as £177 would be about right as that would need coding etc., Try phoning your local Merc dealer or take the key and V5 to them for coding (Hopefully)
Good Luck!

I bought a new Keyless remote for a 2007 Forester from a Subaru Dealer to replace an original one that went bad after 2 years. I have followed the directions in the owner's manual to program it, but can't...


IMPREZA: 2005, 2006, 2007 and
FORESTER: 2005, 2006, 2007, 2008
Check for Immobilizer key on Forester XT models only.
information is always subject to change and correction imp05keylessremote1.jpg
new remote for 2005 Imprezas.
This is not the same remote as the 05 Legacy/Outback remote which also has truck/gate release on the front and a red panic button on the back.
Lock: press Lock button for 2 seconds or so to lock car, and arm optional security system. The car with chirp once and turn signals flash for locked, 5 short chirps and signal flashes if any door is not fully closed. The dome light goes on for 15 seconds and ignition key ring (if present) will light for 30 seconds when unlocked.
Unlock: press unlock one time for driver's door, press again within 5 seconds to unlock all doors inkling rear gate (wagon). The system does not open the trunk.
Panic mode: press and hold lock button for approx. 3-4 seconds to activate Panic mode. I panic model the horn honks and turn signals flash until either the lock or unlock button is pushed again.
Finder mode: Press lock button 3 times within 5 seconds to activate Vehicle Finder mode. The horn will honk once and the turn signals will flash 3 times
Distance: works within approx. 30 feet depending on battery strength, nearby concrete walls and etc.
Audible Chirp On-Off: the system will chirp when locked or unlocked. To turn OFF the chirps, unlock the door and then push both lock and unlock buttons at the exact same time for 2+ seconds. There will be 2 chirps indicating the the audible is off. To turn the chirp back on, repeat the process and the system will chirp one time when it is back on.
Battery: as the battery ages it will only work as you get closer to the car. When a battery is replaced, the transmitter must be re-synchronized with the Keyless control unit. To synchronize, press the lock or unlock button 6 times.
Programming: 4 codes may be programmed.
Sit in driver's seat and unlock all doors. Open and close the driver's door
Turn the ignition key from LOCK to ON position 10 times within 15 seconds. Be sure to stop at both lock and on. The horn will HONK once to indicate transmitter programming mode is activated. Leave key in LOCK position and don't remove it from ignition.
You now have 45 seconds to complete the programming as below.
Open and close driver's door again.
Push either lock or unlock button on the remote you want to program. The horn will honk 2 times when successful.
To continue and program other remotes at the same time: open and close the driver's door and push lock or unlock on the remote. The driver's door must be opened and closed between each remote you want to program.
Done programming? remove the key from the ignition and the horn will honk 3 times.
DELETE old codes? Reprogram 4 times, it will overwrite old codes.
Alarm Security System: optional on all models. When locked there is one chirp (can be turned off, see above), the turn signals will flash and the red 'security' light will start to flash once every 2 seconds except for STi which flashes twice every 2 seconds.
There will be 5 chirps if a door, hood, and trunk or gate is not fully closed
You can also arm the system by using the power lock button on the driver or passenger door as you get out of the car and then closing the door behind you.
Disarm the system: push unlock for 2 seconds
Lost remote, alarm activated? When you can't use a remote to turn off the system: open the door with a key or try to start the car and the horn will start to honk. Turn the key on-off 3 times within 5 seconds and the alarm will go off and you can start the car. It's simple!
VALET mode: To set valet mode or just to disable the security alarm system: 1. unlock all doors 2. physically open the driver's door 3. hold the UNLOCK button on remote for 2+ seconds. The red 'security' light will then flash 2 times a second until the car is turned on.
System has been Tripped (except for STi): if you unlock the door with the remote and it chirps the signal light flash 4 times, the system has been triggered;
Identification mode: To find out what happened and why the system was triggered:
Open and drivers door, leave it open. Turn ignition key from LOCK to ON 2 times and then leave in LOCK position.
Tripped code: 1 security light flash: a door has been opened, 3 flashes when the impact sensor was triggered, 4 flashes when the ignition was messed with or battery disconnected

Program 2004 mercury mountainer garage opener


Verify the hand-held transmitter is operative.
Prepare for programming the universal transmitter by erasing all three channels (hold down the two outside buttons until the red light begins to flash [20-30 seconds]). Release both buttons.
Select one of the three universal transmitter channels to be programmed by pressing the desired button
Hold the end of the hand-held transmitter 25-51 mm (1-2 in) from the front surface of the universal transmitter so that the red light can still be seen
Use both hands to press the hand-held transmitter button and the desired button on the universal transmitter. Do not release either button.
Hold down both buttons until the red light on the universal transmitter flashes, first slowly and then rapidly. Release both buttons when the rapid flashing begins. The universal transmitter has successfully learned the new frequency signal and can be used in place of the hand-held transmitter(s).
If the hand-held transmitter appears to program the universal transmitter but does not open the garage door, the garage door opener may have a code protected or rolling code feature.
To operate, simply press the appropriate button on the universal transmitter. The red light is on while the signal is being transmitted.
IF THE GARAGE OPENER HAS ROLLING CODES---
program as above then------
Train the garage door opener receiver to recognize the universal transmitter.
Remove the cover panel from the garage door opener receiver.
Locate the training button on the garage door opener receiver. Location and color of the button may vary by garage door opener manufacturer. Refer to the garage door opener instruction manual or owner literature.
Press the training button on the garage door opener receiver for 1-2 seconds.
Press the programmed universal transmitter button for as long as the universal transmitter red light flashes (1-2 seconds). Release the button and re-press the button to confirm that the universal transmitter is trained to the receiver.
The garage door opener should recognize the universal transmitter.

Programming the garage door opener


Homelink Garage Door Opener Programming Procedure:

The procedure described below was successfully applied to a 2005 Jaguar S-Type.

To begin with, several attempts were made using the programming instructions contained in my Jaguars owners manual. Though the procedure described in the owners manual was straight-forward and understandable, I was unsuccessful in getting the vehicles remote to make my garage door opener function. The particular garage door openers I have are both made by Genie. Both openers utilize the Rolling Code feature.

To begin with, be sure to clear previous codes on your Jaguars garage door opener by first turning (rotating) the ignition key to the I position (first notch). Next, simultaneously hold button 1 (left most button) and button 3 (right most button) down until the middle buttons red light changes from continuous on to a rapid flash. This process takes approximately 20-25 seconds. What follows is a two part process. In the first part, get your Genie portable remote and hold it near (approximately 3 inches away from) your Jaguars garage door opener console buttons. Choose which button on your Jaguars remote you wish to dedicate to your Genie door opener and simultaneously press and hold your Genie opener button and your Jaguars opener button. The red light on your Jaguars center button (button #2) will light up and within 1-2 seconds will begin to flash rapidly. You have just completed part 1 of the two part process.

Part two: Now it is time to utilize the Learn function on your Genie garage door opener. Press the Learn button on your Genie garage door opener. The red LED adjacent to the Learn button will begin to flash. You now have 30 seconds in which to program your Jaguars opener button. Using the same button you just used in the part 1 procedure, press and hold the same button for several seconds. As before, your Jaguars red light in the middle button will light up and within 1-2 seconds, it will flash rapidly. Release the button you are programming. Now, here is the key piece of information! Once again, press and hold that same button. Once again, the center buttons red light will flash rapidly. Release your newly programmed button. This procedure proved successful in my application. Here is what has just happened. The first time you pressed your Jaguars remote button tells the Genie opener that it exists and that it is a viable candidate for making your life easier (opening the damn door). The second time you press your Jaguars remote button confirms to the Genies rolling code that your Jaguars signal is legitimate and is to be trusted from then on.
