The remote I'd like to duplicate is all black, dimensions 2 1/8 x 1 3/8 x 1/2 inch.
If you open one of these, the insides (back side of the circuit board) should look like as shown in the TSB 40.95.02, as seen in the TSB section of the 164 Digest web site. There should be a small label with a code such as AxxxBxxx.
Is for a 91-93. Pics would work.
thanks
