Question 1

What is the cheapest way to handle all-keys-lost on my 2023 S90?

Accepted Answer

Call a mobile locksmith who actually works on SPA-platform Volvos before you call a dealer or a tow truck. All-keys-lost on this car requires professional diagnostic equipment to wipe the stored key memory and re-enroll new fobs from scratch. There is no ignition-turn sequence or button trick that gets you around that. Dealers often quote a significant wait for parts plus a programming appointment on top, and if the car isn't drivable, towing eats into your budget before anyone even touches the key system.

We handle all-keys-lost on site in Ventura. No tow, no appointment pipeline, done at your location. If you want to stretch the value further, get two fobs paired in the same session. The diagnostic connection and key-memory reset only runs once regardless of how many keys you're adding, so the second key costs you a lot less proportionally than the first.

Question 2

Can you delete a lost or stolen S90 key so it can't start the car anymore?

Accepted Answer

Yes. The key management process on this vehicle's security system includes a full erase of all previously registered fobs. When we run a new key session, the system clears every stored key and only re-registers the ones physically present during programming. A key that wasn't there during that session is deauthorized permanently.

One thing worth knowing: Volvo's connected services can remotely lock the car, but that is not the same as erasing a key from the immobilizer. A stolen fob that is still registered can still attempt to start the vehicle. Remote lock is a convenience block, not a credential wipe. The actual erase requires the programming procedure. If a key went missing and you want it fully shut out, that's the job.

Question 3

Does my S90 smart key have a hidden emergency blade inside it?

Accepted Answer

It does. There is a small release on the fob body that lets you slide out a mechanical key blade. The driver door has a physical lock cylinder behind a cover on the handle, so you can get in manually if the fob battery dies completely.

For starting the car with a dead fob, you don't use the blade. Instead, place the fob against the marked area in the center console. There is a short-range passive antenna built into that zone specifically for this situation. Hold it there and press the start button as normal. A lot of S90 owners find out that spot exists for the first time while standing in a parking lot reading the manual on their phone.

Question 4

I bought a replacement fob online. Can I just bring it to you and have it programmed?

Accepted Answer

Sometimes, but there are real risks with this approach on the S90. The fob has to be the correct configuration for this generation of the vehicle security system. A fob that looks identical and even carries the same factory FCC ID on the label can still be configured incorrectly internally, and those failures don't always show up on day one. As described above, some mismatched fobs pass the first authentication layer and only fall apart days later.

If you already bought one, bring it. I'll read it before committing to programming. If it checks out, we proceed. If it doesn't, I'll tell you upfront rather than program something that's going to strand you in a week.

Question 5

My S90 fob range has gotten noticeably shorter over the past few months. Is the fob dying or is something wrong with the car?

Accepted Answer

Usually the fob. CR2032 cells in this application can measure a nominal voltage but still lack the current output to drive the transmitter at full range. A battery can test at 3 volts on a cheap meter and still behave like it's low under load. Swap it fresh and retest at your normal distance. If range comes back, you had a soft battery.

If a new battery doesn't fix it, the transmitter inside the fob can degrade over time, especially if the fob has taken a hard drop. That's a fob replacement situation, not a vehicle-side problem. The vehicle's receiver antenna almost never fails in isolation on these.
