Baby, when you're far away from me
Call me up on my cell phone
I feel your vibrations come through the phone
Right into my heart

If you wanna be my caller
I'm pleased to be your receiver
I know when my favorite melody sounds
That you're on the line

Suddenly, suddenly, something happened to me
Suddenly you appear with the key to my heart
Suddenly, suddenly, something came over me
And you set me free, you're the key to my heart

Until you are here with me again
I don't mind being your call girl
If you are alone, just lay yourself down
In my answering machine, oh, oh

You know you can keep me satisfied
Just by being under cover
There's no one I'd rather want to have
Inside my phone

Suddenly, suddenly, something happened to me
Suddenly you appear with the key to my heart
Suddenly, suddenly, something came over me
And you set me free

And suddenly, finally, this is pure ecstasy
Suddenly you appear with the key to my heart
Suddenly, suddenly, I will never be lonely
You are my only, the key to my heart
(The key to my heart)

You're all that I ever and it's now or never
You're forever the only one

Suddenly, suddenly, something happened to me
Suddenly, suddenly, suddenly, suddenly, suddenly
(The key to my heart)

Suddenly, suddenly, something happened to me
Suddenly you appear with the key to my heart
Suddenly, suddenly, I will never be lonely
You are my only, the key to my heart, the key to my heart
