Question 1

Do I have to go to the Volvo dealer to get a replacement key for my 2016 S60?

Accepted Answer

No, but you do need someone who has the right equipment for Volvos specifically. That's the real barrier. This isn't a vehicle where you can walk into any locksmith shop and expect them to handle it. Forum threads are full of S60 owners who called eight or ten locksmiths and got turned away before finding one who could actually do the job.

The dealer is not your only option. A mobile locksmith who carries proper diagnostic tooling for Volvo can program a replacement fob on site, in your driveway, without you scheduling a service appointment and waiting days for a key to be ordered in. That's what we do. If you're in Downtown El Cajon or anywhere nearby, you don't have to make the dealer trip.

Question 2

What exactly is a smart key and how does it work on the 2016 S60?

Accepted Answer

The fob for the 2016 S60 is more than a remote. It contains a transponder that has to be registered to your specific vehicle's immobilizer before the engine will start. The car checks for that paired signal every time you try to start it. A blank fob that hasn't been programmed, even one that's the right shape and has a fresh battery, will get rejected. The car won't start.

The fob also carries a physical blade that folds in. That blade is cut to your locks and ignition cylinder. So there are actually two things that have to be right: the blade cut and the transponder programming. We handle both on site.

The battery is a CR2450. Worth knowing because it's less common than the CR2032 cells in most fobs, and putting in the wrong size is a quick way to cause intermittent problems that look like something worse.

Question 3

How long does Volvo dealer key replacement actually take?

Accepted Answer

Longer than you'd want. Dealers generally don't keep S60 fobs on the shelf. The key gets ordered, and owners consistently report waiting anywhere from several days to a few weeks depending on stock and where the dealer sources their parts. Once the physical key finally arrives, the programming itself takes only a few minutes. But you've already been waiting.

Mobile service skips that entirely. I bring the fob with me.

Question 4

My 2016 S60 is showing a key warning on the dash and sometimes won't start on the first try. Is the fob failing?

Accepted Answer

Maybe, but start with the battery. The CR2450 in these fobs doesn't give much warning before it affects performance. A low battery on this system can cause intermittent start problems and key-not-detected warnings that look like a pairing or immobilizer issue when it's actually just the cell losing voltage. Replace the battery first and make sure it's seated flat against the contacts.

If the warning comes back after a fresh CR2450, then the fob itself warrants a closer look. The transponder could have developed a fault, or the fob may have taken enough physical wear that the internal antenna connection is intermittent. Bring it to me and I can read the fob and check whether it's still communicating cleanly with the car before recommending anything further.

Question 5

I lost both keys to my 2016 S60. Is that a much bigger job than just adding a spare?

Accepted Answer

Yes, and it's worth understanding why before you're in that situation.

Adding a second key when you still have a working one is a relatively clean job. The car already knows a valid key, so the process is about adding to what's registered.

All-keys-lost is a different scenario. With no working key present, accessing the vehicle's immobilizer system to wipe and re-register keys is a more involved process that takes longer and costs more. On Volvos specifically, the job requires deeper access to the body electronics than a standard add-a-key does.

The practical advice: if you currently have one key for your S60, getting a spare now is the lowest-cost version of this problem. Waiting until you lose that one key turns a moderate job into a much more involved one.
