My current programmer has lost some lines on the display and does not allow to reprogram it. Otherwise it is working fine according to the pre-existing settings.
Can anyone please guide if this is a matter of a battery change or the whole unit needs replacement.
Is the replacement with a new LP522 a straightforward DIY job without the need for rewiring ?
Thanks in Advance
Zack
