Can someone confirm that there is no way to reprogram a remote without the original code?

I bought a used key/remote off of ebay and my dealer is telling me they need a code or the vin from the car this came from in order to match it to my car. Seems kind of backwards to me. I thought I read that it was possible, but now I'm having trouble finding that again. Maybe I imagined it

The dealer is right. The key fob needs to be programmed by them.
Yep, toss it. I did the same thing. Those who sell used Volvo key remotes on Ebay are scamming you or just plain stupid. There is no way to reprogram them without the bar code that came with them when new. You're stuck buying one from your dealer and paying for the fob, and the labor charge to program it and a software download from VIDA.
Thanks. I'll just have them cut me a key and attach it to this now non-functional remote. It's just going to be a spare anyways. Spending $100 for the key cut is enough, I don't need to spend another $200 for the remote just to have it sit in a drawer.

IIRC, they have to program the key as well to work with your car. No problem, just more $.

They do have to "pair" the key to your car. There is also a limit to how many keys can be paired... it's either 3 or 4.

If you're replacing a remote, take the circuit board out of your old one and swap it with the new one. You'll still need to have the key cut and the immobilizer chip and paired to the car. Other than that, there's not really much else you can do.

I replaced my normal keys with the fob style keys. Instead of reprogramming i just cut up the old keys and removed the transponder. Then I made a hole in the fob and secured the transponder. (I think I read it on this forum somewhere)
So cheap fob + old transponder + newly cut key = relatively cheap conversion.

Different story if you don't have a spare key to begin with of course

Even if you had the VIN the remote may have come from, no way to program it.

Only the original remotes that came with your car could be reprogrammed without the 16 digit and 8 digit codes. One possible scenario would be if your CEM is replaced, the codes would need to be put back in the CEM. When the CEM software is Reloaded, those codes are VIN specific and put back as if the car was new again. Supposedly if you ever had a new remote programmed or replaced, and the CEM is replaced, the remote codes are supposed to be downloaded with the software reload. However, I can say this doesn't work 100% of the time and the dealer will usually warranty any remote that fails to work after a CEM reload.

Ignition keys can be reprogrammed if CEM S/W is reloaded but remotes need the codes and usually the codes are thrown away after initial programming. At the dealer I worked at, I used to peel the code stick off the remote package and put it on the back of the ticket. Tickets were scanned and stored for future reference and notes. So we could actually look up the remote codes if something such as a CEM reload didn't load the replaced remote codes.

Frankly, its more of a revenue generator for the factory and the dealer. Requires the customer to visit a dealer and lets them charge pretty much whatever they want. A key and remote with separate programming for each could cost some people $400 or more. Think about that the next time you let a little one play with your keys!

There are some Independents that possible could program new key and remotes but they still have to buy the parts from the dealer and the software from Volvo and pass the cost of leasing the Volvo Diagnostic Program VIDA which allows communication from the car to computer. So the cost would likely be the same. Sux

If you have a working key or fob it's possible to clone them with this new device. I successfully cloned a key for my 04V70 with an IP-48 chip I got on e-bay. The only issue is the car will recognize the key or fob as the same one you cloned. So I have two key #2s now my memory seats and mirrors go to memory position #2 with both keys. My fob was still working so I didn't clone it, but I did test its abilty to read the fob so it should be able to write to it also. It's a VHorse VVDI Mini key tool and cost $99. I picked up an additional 10 IP48 chips from VHorse for $20 in case the ebay one chip that came with the key didn't work. It does take a little while to program because you have to read all 8 or 16 codes individually before it can configure the writing process.

good to know - I cloned my key fob to a new eBay fob using VDASH recently worked perfectly, so I now have a 3rd independent key programmed for my car. Aside from VDASH & DICE no other tools or knowledge required.
