Remote Key Fob Ploblems

[dibsLPG]

Hi guys, need some wisdom please,

My Key Remote is playing up (IS200SE) It sometimes dose not unlock the doors, I keep pressing the unlock button, lock & boot open etc. , light flash's but no joy so I manually open the door and of-course the Alarm starts up :tsktsk: , start the car and it stops.

It seems to be intermittent. I only noticed this upon my return from holidays when it was left parked up for about a week.

I have replaced the Battery 6 months ago.

Any recommendations of the Type/Make of Battery to replace it with just to eliminate it?

Any advise as always appriciated,

May not be the Battery, there may be interference with the signal.

Does it just do it when your parked at home or everywhere?

i have the same problem, swapped both battery's when i got the car (one in the main key,and one in the valet key). Now the main key (with boot opener) is flat! <_<

The distance i could use the key started to get really small no matter where i was, now it's got to the point where it just doesnt work.

Fortunately though, they're only a couple of quid and really easy to buy, unlike the size 0 phillip's thats needed to open the damn thing. :)

Rikos; it does it randomly not matter where i am, at work its in a carpark so no major interferance..

corsavandal; i am about to replace the Battery on the fob, any Type that you can recommend? or should I go tothe stealers to buy one from them?

Good job you reminded me about the valet key so i might give that a try to and replace the batt to since it has never been used has far has i am aware even by the last owner..

Cheers for the info, will update my progress soon.

I thought the Battery charges itself when it is in the ignition?

Sorry mate it doesnt do that - it is a standard non rechargeable Battery and would have to have a +ve line built into the key or an induction coil combined with a rechageable Battery.

But for info in 6 years i have had to change the Battery once - if the batteries are only lasting about 5 months either its a cheapo Battery or you are locking/unlocking the car a lot.

If the key remote operation is not working properly try standing about 1M away from the drivers door - then you are in the optimal area for the lock/unlock sensor

You might be right on the cheapo Battery bit Fluff3467

So which is the best type of Battery and where can i get one please?

save me hassle posting the same question in about 5 months time :winky:

Hmm, I can honestly say I've never replaced a remote key fob Battery. I had a Renault for 2 years, a Fiat for 2, a Peugeot for 3 and a Toyota for 2 and never needed to change it and didn't notice any drop in performance. Guess I've just been lucky or had good quality batteries.

Lexus recommend Panasonic CR1632 (Got mine from amazon couple of quid for two) however, mine still plays up at times. I wonder if the actual sensor in the car needs a clean off. Does anybody know where the sensor is located in an is 220d?

It could be the curcuit board button connection . Solder breaks and causes problems. Can be fixed. I bought spare buttons but curcuit was too badly damaged so had to buy new master key from lexus £160. If anyone needs 3 buttons let me know.(will need soldering to board)
