Key completely dead - Clio 172 Ph1

[Jakeeaton127]

Hello,

I’ve just picked up a 172 and the key was dead at first. So I shoved a new 2016 battery in it and it hasn’t made a difference at all. The light doesn’t illuminate and the buttons does absolutely nothing. Anyone know a fix to this?

The car was sat since 2018 so is there a chance it’s lost its coding to the car? Also it has a replacement passenger door, the lock on that doesn’t work with the key or interior central locking could that be something to do with it?

The red LED should light up when you press the button. It could be one of the solder joints have gone or corrosion on the terminals for the battery maybe?

Stick a picture of the PCB up mate

That’s what the insides of the key look like. I’m guessing that’s what you’re after.

I’m definitely going to try what was left in the project forum for the car when I’ve got a minute.

What does the otherside of the green PCB look like?

Is that corrosion on that pad?

OEM keyfob uses a CR1220*. Might not be your issue, but my microswitch needed re-soldering as the joints had broken.

*on a 172 ph2 at least, is a ph1 different?

Doesn’t look like it in person, it was a bit dirty though. I cleaned it and it didn’t do anything

Might be it, I just went with the battery it already had in it. @James did you change the battery in your ownership?

It might be a non-OEM (or ph1 specific board then). Both batteries are 3v so if it worked before its probably right tbh. Be interested to find out what it is. if you have a multimeter you can at least check button continuity.

Don't remember doing so mate, no

I haven’t got a multimeter to check it, another ph1, a normal one, on YouTube used 2016 batteries but it had two in. The internal of the key was completely different though so this could have a different board in it.

My money is on this. Was quite a common issue wasn't it?

Just reflow the board, use a heat gun or hairdryer

Baterry must be fine, I have never seen one. My ph2 keys have always looked like this:

I would suggest jumping the switch but you have to close the case to complete the battery circuit

I think it's quite common as far as broken fobs go

Just reflow the board, use a heat gun or hairdryer

This is a good shout, even if it's just some fresh solder on the micro switch and go from there

Mine looks completely different inside, the battery isn’t attached to the circuit board like that. It’s sat inside the plastic on the key.

I’ll have a look into the microswitch and reflowing the board.

I would mind if the bloody passenger door locks but it doesn’t so I thought I’d try this first of too see if it works.

Welcome to Clio ownership, I would suggest buying a multimeter ASAP - you will more than likely get your moneys worth...

hopefully, it doesn’t give me any other electrical or key related issues once I fix it. However the chances of that are pretty much 0

Im quite tempted to just buy a new key for it and just get that synced to the car. Im not sure how much that will cost though.

See if anyone here local to you has CLIP and knows how to use it. Think you can code keys through that?

I shall have a look into that. in guessing that's the old Renault dealer/diag software.

im planning on getting a spare key for the car in the near future anyways so I might as well replace it.

If I could fix the manual lock I could do without the central locking for the time being.

Yeah that's the one mate


Does the key operate the barrel at all?
