I just bought DL2520 to replace the CR2520 batteries in my key. Neither one has been working for a while so I put the key in both the door and in position 2 in the ignition to see if it would get reprogramed, but neither key is working. Can someone please help?

 

According to the owners manual for our model year, the correct batteries are CR2025. Did you just make a typo in your original post or are all these batteries interchangable?

Also from the owners manual...

Synchronizing Remote Control

The system may have to be resynchronized,
if the transmitter is
without voltage for several minutes.
To synchronize system, aim transmitter
eye (1) at vehicle and briefly
press transmit button (lock or unlock)
twice. Within approx. 30 seconds,
insert key in steering lock and turn it
to position 2.
The remote control should once again
be operational.

 

Thank you Bob - I did transpose the numbers, but just when typing. I have the DL2025, it isn't working so I ordered the CR2025. I will try the re-synch instructions for grins, and await the arrival of the new batteries.
I greatly appreciate your help
