Pincode for hyundai accent with vin number NHLCG4IF852071640

Go to a service dealer for your vehicle and they should have a record of the key code for that vin number. The only problem is that you may have to prove ownership of the vehicle first.

A Hyundai dealer may be able to make you a new key from the VIN number on the dashboard. However, you will need to prove you own the car, as they get requests regularly for a new key with a stolen VIN number.
Be blessed.

My hyundai accent giving p1801 and p1805 the car dont start what should i do.regds Maxwell,

P1801:------- Immobilizer Transponder Error. ------------------------------ P1805/P1806:----- EEPROM Error/VIN Mismatch. ------------- In most cases the error 1801 and 1805 comes up together.But error 1806 is very rare.But 1806 and 1805 both are error related to same problem. P1801 and P1805/06 are immobilizer errors. Does your car have an anti-theft
device which reads a transponder in the key? If so, the problem is with
this system. The immobilizer problems are typically with thelock cylinder sensor. --------------- Keep updated with further queries if required.Thanks.

It will be much easier to go to Hyundai with the vin number, proof of ownership (a title) and a valid state issued photo I.D. and have them make you a new key.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

if you had the original code you were able to change the code to your own,so if someone has changed the code,your fu....either repair or replace with a decent unit.(repairs cost more than a new unit.)

Could be as simple as a blown fuse for the ETACS module, but it sounds more like a problem with the anti theft immobilizer system. Does your car have remote keyless entry? And is the key you are using a factory key or one someone made? (factory key will be encased in bulky black plastic with hyundai logo) The transponder in the key might have worn out and is not talking to the car anymore. Some hyundais use the radio antenna to receive the signal, is there an antenna on the car? Is it hooked up? If it is a problem with the key and immobilizer system, It will unfortunately need towed to a dealer and reprogrammed.

you have to tow car to dealer - then they cut and program key - yes,it is a bit pricey!
internet offers ways but will only work couple times - repos do same thing

Have you called the dealer?

dealer item only by giving them your vin number, no other way.
sorry
