How far can your keys unlock/lock your doors?

[Guest GASTON]

I am somewhat frustrated on the short distance my keys for the M Class can unlock/lock the doors. So I am wondering if this is normal. My previous W211 can unlock/lock my doors even beyond 30 feet. But my 2008 M Class can only do it at not more than 15 ft. Are these the same distance you get with your keys or are my keys faulty? :banghead:

rgds.

Mine can work even at around 20m away (is that around 60ft?)

I'm pretty certain my keys worked even at 30m, I remember being extremely impressed with the range!

hmmm your car has a higher COG, so maybe the box is at a higher height :banghead: but than normally if box higher sure longer range!

Maybe try changing the battery?

I didn't really measure the distance, just Argah-ration. But i feel that 30m is possible, cos it works from quite far.

Mine sucks big time! Practically have to stand next to my W210.

[Guest funng]

my w211 surely can 30m or more. at night can on from far to get the lights to turn on to see where I park.

i think maybe battery? I use the open windows with key function, so i think more "eat" battery. my range dropped compared to when new.

I am sure mine exceeded the 30m range, ever did it from my house which is 4th storey high.

You better send it in to have a check and at the same time can do some destress there :tazzie: hahaa.....

heheh same, my range dropped too, think due to me always use the key to open and close top.

[Guest GASTON]

thanks for your reply, guys! Both my keys gives me about the same distance. Will definitely send back to recheck.

Cheers! :iconsalut:

Yes that will kill your key battery. I remember I had to use the manual key to open my door previously because the battery completely ran out. You can just open the key and pop a new battery in though. It's one of those flat circles.

I think it is a Lithium Coin battery CR2025

U can get this off at superrmart racks.

Should be the same key as everyone else. Non-rechargeable as far as I know.

U are rite again!

Lithium "coin" cells(common CR2025, CR2032) are mainly classified as primary cells and are non rechargeable.

Same same as your alkaline cells(your typical AA, AAA, C, D), silver or manganese coin(watches) or zinc air (hearing aids)

Secondary cells like Nickel Metal Hydride Rounds & Buttons, Lithium Ion, Lithium Polymer and a few rare types of Lithium coin are rechargeable.

Any U kakies have problem finding a replacement battery for your personal use, Unker might be of help to U at no charges. :yumyum:
