what are you using for a smart key fob tester? I have seen a few that show different frequencies, on them, but I'm not sure how you are to tell which fob would have which frequency.
I tell most our customers that if they have a message on their DIC, then it needs a new battery, but some still want them tested. With the tester that we have it just shows if it is putting off a signal, but not whether it's putting off enough signal to allow the vehicle to start.

We have the Bosch EL-43241-A Remote Keyless Entry Tester which is ok for a quick and simple test.

I prefer to use an actual volt meter to see if the remote battery is above 3V.

You can get a cheap volt meter at Harbor Freight.

Its a keyfob battery, why test them? they are under $5 retail.

We use a Toyota RF Detector.

It has a red LED that that ranges from weak to strong when you press the buttons on the fob

PN is 00002-09001-01

works well for us

For years, our GM fobs, the contact tab for the battery would break off the board. It helps to see if they are infact transmitting.

99% of the time it is just a battery tho, youre right

I cannot count the number of customers that have come in...."According to You Tube this was what I needed to do and this POS still does not work, put a new battery in........" Split the case open and the battery still has the protective tape on the negative side.

I've had the same thing happen many times. Cannot help but to laugh.
