Default C70 key fob replacement.

hi I have been searching the posts but I canít quite find the answer that Iím looking for so If any one can help with this.

I have recently just bought a c70 T collection 2004 as I own an old v70R and love the feel of the old volvos, the drive the looks, the comfort, IT ALL!

My question to you all is regards a key fob replacement. I have called so many places and getting quoted ridiculous prices and most places canít do Volvos. So what Iím looking to find out is- if I buy one online (not eBay) can these easily be coded to the car. I have seen a company in US selling these and wonder if the coding will work or is it different UK to US.

Or

If I buy a used one already coded to another car can this be wiped and then recoded to my car?

Or could I use one for the time being from the v70 and try to get that recoded?

Thanks for any advice given I appreciate the time on this, I just canít seem to find out the correct info and finding a lot of conflicting information, but I guess thatís the internet for you.

Thanks.

Tof. 🤟

Hi Tof

If you can find a Volvo dealer, or an independent Volvo service business in your area, they will be able to sort you out.

The new or used fobs can be programmed to your car. It will only take 5 minutes. Or if you know what to look for you can buy a used pair of fobs and a module from a C70 and just plug the module in and the fobs will work. Look for a C70 in the For Sale section of this forum.

Is Alloa near Stirling?

Hi Steve.

Thanks for your message, your reply has been very informative and gives me the answers that I was looking for. Seen so many different comments/status in regards to fobs and was real unsure of what the script actually was. My plan is to try and buy 1 or 2 fobs either new or used from a breaking car say and get them coded to my car (c70). Failing that the option of sourcing a set of fobs and the module will be the way.

Yeah Alloa is just outside Stirling about 7 miles out. I will have a look atm for c70 for sale on here.

Thanks ur advice has been great hopefully I can get somewhere with it as not having the fob it driving me mad as silly as that sounds.

Tof. 😃

Default Key fob - ebay

Hi Tof
Just FYI. I previously owned a MY 2001 C70 Coupe that needed a new fob. The guts were fine but the plastic case had broken into pieces. Bought the fob casing only from ebay, placed the original guts in it, problem solved without the need for re-coding. A new battery was also supplied at a total cost of £3.49, free postage. Hope this info. is useful.

Some time back, I bought a C70 (but don't have it any more).

It came with 1 key and 1 fob. Fine as long as I don't lose them.

But, in a breakers I found a pair of fobs and the appropriate module for a reasonable price. Went to my local indy who got me a spare key cut and coded, (a bit expensive, but...) and was even kind enough the get down on hands and knees and grovel (my arthritic knees not really up to that!) under the dash to swap over the module as well.

I also felt reassured (aka smug) to have a full set.

I think technically a "full set" would be 3 keys/fobs!

Default Coding Key Fob

Have seen used fobs on eBay but notice that they mention a specific frequency in the listings. Is this crucial that I get the correct one and if so, how do I find what mine is as there is nothing marked on the one I already have?

Some years ago I bought a spare for a SAAB and the dealer was unable to code it to the car so that was a waste of money (although the dealer didn't charge for the unsuccessful attempt).

My V70 is a 1998 MY so will any 3-button fob be suitable or is it only later VIDA cars that can have new fobs coded to them?

TIA

The 98 V70 uses a volvo scan tool like this
https://www.youtube.com/watch?v=DZEoZDjvNMM
and requires a 4 digit pin to enable the car to accept new remotes.

in theory if you know your pin you can program it yourself with a generic obd2 usb type interface e.g. an elm327 ebay job.

you can work out the frequency of the fob based on the part number on the back of the case, however if the case has broken and been replaced the new part number will most likely be different.

the antenna for the fob should be a box attached to the back of the instrument cluster, it will have a big colourful number on it to tell you the frequency it is expecting, but that doesn't help much when choosing a fob.

I think its mostly region specific so as long as its from here and you don't buy one imported from america or japan or something you should be ok.

My fob has a part number on the back but I presumed that was for the case only. There was a white label on the back but it has all been worn away so nothing is readable.

I did extend the antenna some time ago and took photographs so I'll dig those out to check the details rather than take the dash pad off.

From what you say I guess it may be worth taking a chance on used fob and asking my local dealer to code it. I've done without a spare fob since I bought the car several years ago (have a spare key though) but have always had it in the back of my mind as to how I would deal with losing the fob.

Thanks for your reply.
