How do I program 2001 Volvo V70 XC new Locksmith cut ignition key and how do I program Key FOB for this vehicle

Volvo not Volo, sorry. all answers by me USA< so, here goes.
the #1 design purpose of IMMO is to do exactly that.
It stop thieves dead in their tracks. or owners, lost keys.
the car came with 2 keys. lost both?
most modern cars if you have 1 key good a second key is allowed to be made by you DIY, and is covered how in the glove box guide.
lost all keys? not told why asking for bypass at all.
but lost keys are a huge problem and answered 100000 times on the internet and here and by your car dealer.
check all fuses first, so that all IMMO related models work.
then scan the PCM for (only key failure)
then.
1: tow it to the dealer.
2: tow it to locksmith ask for permission and say volvo.
3: call for remove locksmith home service, call say volvo

if scanning the PCm show gross faults in the key decoder or related parts, only 1 is a cure.
if DTCs show as WRONG key only a lock smith may help you.

the users guide quoted to you now see at makers web site
and glove box

Keys
Two types of keys are provided with your car; master keys and a service key. The master key, the remote control, and the central locking button may all be used to lock and unlock all of your car's locks.
The service key operates the driver's door and the ignition switch. It will also fit the tailgate lock cylinder on models outfitted with a factory installed third seat. The service key is intended to help deter unwanted entry into the glove compartment.
Turn the key once to unlock the driver's door and the fuel filler door.
Turn the key again (within 10 seconds) to unlock all doors and the tailgate.
One turn with the key towards lock in the drivers door locks all doors and tailgate.
Use the switch on the front door armrests to lock/unlock the car from the inside.
Immobilizer (start inhibitor)
Each of the keys supplied with your car contains a coded transmitter. The code in the key is transmitted to an antenna in the ignition switch where it is compared to the code stored in the start inhibitor module. The car will start only with a properly coded key.
If you misplace a key, take the other keys to an authorized Volvo retailer for reprogramming as an antitheft measure.
*This key operates only driver's door and ignition switch/steering wheel lock.
Key Fob Remote Programming Instructions for a 2005 Volvo V70 SORRY, THERE ARE NO KEYLESS ENTRY REMOTE SELF-PROGRAMMING INSTRUCTIONS FOR THIS VEHICLE https://northcoastkeyless.com/2005-volvo-v70-keyless-entry-remote-fob-programming-instructions/


every key shop I think tell this same story.

and you must scan the PCM to see that it is ONLY the key failing.
this is first after fuse

if it has a battery ( Programmable key) go on e-bay or to a locksmith and get a blank key with fob pocket
have the key cut then install the internals into the new key fob
if you want a whole programmable key, that will set you back around $500.00 from either the locksmith capable of programming the new key or from a dealer

So your lights come on ? Need more info.

Assuming it's a standard GM half moon style key fob, you can get replacements soon many sources including dealerships, locksmiths, and ebay.

Programming depends on whether you already have a working key?

If you don't, you will have to go to a dealer or find a locksmith who has the right equipment (I suspect not many do).

THis works for Holden Commodores of that era, most GM products should be similar:
If you have a working key, it's relatively straight forward, as the car can program new keys.
1 remove screws holding key blades into the remote heads of both keys.
2 remote the key blade from the *new* key and put aside.
3 insert old (working) key into ignition and start the car.
4 with car running, carefully slide the remote head off the key in the ignition barrel. Car should stay running.
5 carefully slide new remote head onto the old key blade sitting in ignition. Make sure the metal contact inside the key blade insert makes contact with the key blade. Make certain the small contact pin on the facing edge of the remote makes contact with the metal slide ring on the outside of the ignition barrel - these two contacts form a circuit.
6 The key fob should program almost immediately, but leave the fob in position for 30 secs to a minute to ensure its done.
7 turn car off and reassemble keys.
8 test all functions of new key - remote entry and engine start.

(get key blank cut by a locksmith before commencing the above!)

Just replacing the battery in a key fob should not require any reset! If the power door locks work using the remote or key then it could be the switch is faulty!

The key fob has to be programmed by a dealer. The car has to be connected to the Volvo computer readout/program system

So good news and bad news. Bad news is the remote portion for a 1998 Cadillac Catera Key Fob requires profressional programming. We suggest using a locksmith, they should save you some money compared to the dealer.

The good news is if you need to program another transponder key, you can do that yourself. Get a spare key cut and simply follow the instructions below:

Should have a key fob.  You can buy a used one and the dealer can program it.  You can not program it yourself.

If your car has the xenon headlights, it might be a faulty xenon ballast/regulator module. You car has daytime running lights so they are on at a low power setting all the time.
