I can't access to my wallet

[BTCProFan]

Hello,

I have my wallet in Bitcoin Core old 3 years, and I have some money on my wallet.
I want to make withdrawal, and I can't because... I have my private key also I export wallet.dat.
Problem is if import key to electrum or bitcoin.com I got different public address and in different I dont have money...

I have make one test in another pc and I only replace wallet.dat I got the correct public address.

How is that possible?

Since you managed to import wallet.dat on another computer, why don't you just send all coins to the new address (new wallet) from there?

The wallet follows the traditional way to derive the public key from the private key, so you will see the address as p2pkh address.
You must define the wallet that you want to derive p2wpkh-p2sh/p2wpkh from the address by adding the appropriate word before importing the private key.
The solution above is correct, as you can try with electrum console:

Code:

key = 'your_key'
txin_type, secret, compressed = bitcoin.deserialize_privkey(key)
wif2 = bitcoin.serialize_privkey(secret, compressed, 'p2wpkh-p2sh')
print(wif2)
