Key Fob Batteries
Key fob batteries are an application page, not a new model page. The catalog page lists remote keyless entry among the applications for CR coin cells, and this page carries that application framing forward without adding a new model specification.
For a key fob application, the cell questions are the same as for any coin-cell inquiry: which coin model, which variant, and which tabbed or untabbed form. The CR coin tables on the CR coin batteries page answer the model question; this page does not restate them as a key-fob specification.
Ask for the datasheet of a named model before ordering, and confirm the exact model, the variant, and the ordering steps for that model.
What to confirm before ordering
Which family fits the question? Which listed name, if any, is in question? What documentation is available on request? What are the ordering steps for the named item?
