Annoying remote locks issue
Do anybody know why my remote locks only work about half the time on my 2001 C320. The remote battery is good. I had it reset once at the dealer and it worked fine for about a month or two. Thanks for any advice. Tim

no, they work simultaneously. The FM is the one you can use from long range the infrared you have to aim at the little tiny square by your drivers door handle as well just like you would with a TV remote. FM you don't have to aim you just push the button and unlock but if that isn't working then you would have to use the infrared method. Hope this helps!

Do you have tint on your car? They frequently screw up the Aerial when applying. The aerial is above the roof lining in the centre of your rear window.

I'm glad whoever the previous owner had tint the windows knew what they were doing then! My fob works like a champ. I can't stand untinted windows (plus I can't see as well). Though they didn't change the window felts and the drivers door tint is all scratched up.

Make the tint place pay for new aerial set up - If you search you will find 100s of aerials ruined by the tint guys. Metallic tints can also mess with things

If tinting has been done then water frequently shorts the antenna & blows the RF amplifier or when trimming the tint they cut through the wires/traces as they exit the glass.
Metallised mylar tints frequently ruin radio & remote reception. Radio & remote share the antenna/aerial - Only option - remove & replace the tint.
So we have 3 potential problems.
- The tint itself
- A blown RF amplifier
- A damaged antenna trace in the glass or wiring above the glass
The worse case scenario requires replacement of the rear window. The amplifier replacement is relatively easy.

Yes the Aerial is built into the glass. The Amplifier is mounted above the rear screen on Coupes & in the LHS C pillar in sedans.
