I have one of those older security devices that certain customers received long before it was a mandatory program. I did not check, but I would guess it is about 3 years old. It's a SAFEWORD GOLD 3000. It functioned properly until yesterday. It used to be PIN-locked. But the lock is now gone. It still asks for a 5-digit PIN. But after any combination of 4 digits it now grants access to the challenge routine and delivers valid access codes. Those of you with older devices might wanna check their devices (in the future) if PIN protection is vital to you.
