Hi,

Same thing happened when I replaced mine.

I think you need to lock and unlock the car a few times manually before the new battery is registered with Zoe.

 

Hi,

Thanks, good advice.

Since posting I've found a really good UTube clip at

. Nice finger nails!

And the correct battery is a CR2016.

Cheers

Manual also states you may need to do the following to get rid of 'Low Battery message'

When refitting, proceed in the reverse
order, then depending on the vehicle,
press one of the buttons on the card
four times, close to the vehicle: the
message will disappear.
Note: it is not advisable to touch the
electronic circuit or contacts on the
RENAULT card when replacing the battery.

 

Hi,

Thanks, that could be the bit I was missing.

Cheers,

Hi,

Just an update on batteries. It turns out that the CR2016 was too small & therefore the key card didn't work but the emergency key did...although it didn't switch the alarm off!! But no one takes any notice of car alarms so no real issues with that.

The correct battery is the DL2025 & the card works as it should now.

I can now not only get into the key card in double quick time but also under "field" conditions.

Thanks All.

Bruce

 

Inside the battery cover of my keycard it says CR2032.
Worth checking yours as there may be different types out there.

 

I've just replaced my original battery with a new CR2032. It fits fine and the low battery warning disappeared without the need for any elaborate button pressing.

 

Blister packs of 2no CR2016, 4no CR2025 and 2no CR2032 are available from Poundland for.......£1!

 

Just Checked my Zoe ze40 is CR2032

 

Yep it is the CR2032. And to get access to the battery to change it use the emergency key to prise open the tab holding the battery. I was originally worried about breaking this as it seems flimsy but after watching a YouTube video I found it really easy. And yes the batteries can be really cheap although I have to say I would not necessarily trust a Poundland battery..

 

I decided to give my spare keycard an outing, as it only gets used when the car goes in for a service. After a short while I got the low battery warning, so I replaced the CR2032.

I didn't test it at the time, but when I tried to use it the following day, it didn't work unless I was about 30cm from the car, even pressing the buttons. I suspected a faulty battery, so I put the original battery back in, but it was the same. I thought that I may have damaged the keycard with the flexing required to access the battery, so I got the other keycard out, but it showed the same symptoms.

I tried starting the car in case it needed to re-establish communication with the card, but there was no improvement.

After driving to a friend's (about 30 miles), the keycard was all working correctly when we arrived. I don't know what that was all about. I had changed the battery in the original keycard a couple of times, and never had this sort of problem.

 

So, both keycards fail in one place and then start to work somewhere else? The only thing that I can think of would be RF interference. Any potential strong sources of RF anywhere?

 

It's possible, but there has been no similar occurrence at my home in nearly 4 years of ownership. Strange that it should coincide with changing the battery.

 

The only problem we have had is when the spare key card is in close proximity to the car. That seems to confuse the car e.g. Not enabling auto lock on move away. Ours was in a kitchen drawer that happened to back onto the garage. When i moved the key elsewhere the problem went away
