  1. Try 0182 or 0180 If you have not already read this FAQ - please do so... Lost Radio Code - FAQ, PLEASE READ THIS FIRST Wow! 0182 worked like magic! That is cool, and thanks for replying so quick! I definitely owe you a beer or two Aha - I see you can donate at the bottom - I'll do that - thanks so much! BuddyK
  2. I need my radio code, the one on the card doesn't seem to work (8302) Can you look it up? 1999 C4 6 Speed Black USA CDR-220 Type 4462 Serial W5003094 01/99 Thanks!
  3. This has to do with radio waves. You want to catch the wave with the antenna, so an antenna of appropriate length will make a huge difference. If the transmitter operates at 315Mhz for USA Canada, then the quarter wave antenna would be 226.42 mm. Half wave antenna would be 452.8 mm 1/8 wavelength 0ft. 4 - 15/32in. or 0.113 M 1/4 wavelength 0ft. 8 - 15/16in. or 0.226 M 3/8 wavelength 1ft. 1 - 3/8in. or 0.340 M 5/8 wavelength 1ft. 10 - 5/16in. or 0.566 M so the 130mm beyond the insulation advice doesn't quite make sense to me yet - but I'm not an RF engineer. Does this transmitter operate on exactly 315Mhz? I doubt it - it probably is in a range of frequencies designated for keyfob transmitters somewhere within 10Mhz plus or minus of the 315Mhz listed. This would be the length of wire outside any radio wave insulating mesh or foil I believe. If there were no insulating material, then the measurement could be from the printed circuit board. It's important to know where the measurement should start. Otherwise, you'll get random antenna length and probably random results. Longer is not always better all the time. From what I have gleaned from all the posts it seems that the antenna is being inadvertently shielded inside there by a bundle of wires etc, and it may also be of inappropriate length. I have not done any mod yet, but my 1999 C4 really needs it, so I'm looking forward to this. I have seen many other cars with 100 foot + range, so maybe I can add some antenna and match it up just right - I'll let you know here when I do it.
