Thank you IRstuff Do you know any company well suited to develop this, since it does not exist?

IRstuff Damned, it appears that what I am looking for does not exist. All the smoke/fire detectors are much larger. I suppose the manufacturers have no incentive to miniaturize them, even though it should be technically possible.

Make your own enclosure. Buy styrene sheets (about 1/8th inch thick) and: 1) Score it with an X-acto knive and steel ruler, and break it off along the cut. 2) Use sand paper to sand the edge smooth/flat. 3) Use solvent (in syringe) to bond the several panels together to create the enclosure...

Hi, I am looking for miniature smoke detector chips. Most smoke detectors I found (optical, ionization, or both) are in hand-sized enclosures, but I am looking for one much smaller sensor/chip, around 1x1 inch. Is this technically feasible? Anyone experienced with smoke detectors? Thank...

Could you elaborate on how "Universal" units function? Are they really compatible with most cars? How does the user set them up to work with their car?

The Mercedes key is far more advanced than what I'm looking for. Many cars are still manufactured with basic/low-end key fobs that just lock/unlock doors. I bet these don't cost more than a few $ to manufacture..

MacGyverS2000 Concurred, the low-end fobs can't cost more than $10-$15 retail, which translates into a manufacturing cost of $2-$4 max. That is what I am looking for, no fancy functions. Now the product I am working on is not a key fob, doesn't remotely resemble it, and has other functions...

Thank you. I was thinking more about the cheap-looking GM/Chrysler Dodge keys (which look like they were made by the same manufacturer). These key fobs only have buttons for LOCK/UNLOCK; HORN; TRUNK. I can't see how they would cost more than $6 to manufacture, considering the huge volumes in...

IRstuff That is right, they could just go out and buy a new fob, but our product is different in a way I can't reveal here unfortunately. By the way, does anyone know how much a replacement fob costs? I am trying to get an idea of costs for this feature. Thanks

Thank you all. It seems like there are a number of variables. From what I understand from your comments, it would be impossible, or very difficult, to make out item compatible with ALL auto makers. We are thus considering working only with 1 or 2 large car manufacturers to begin with. All...

MacGyver: Thanks a lot, that's valuable information. Yes I am talking about the simple car lock remotes, NOT remote-starting fobs etc.. To answer your question, I am a bit different in that I don't necessarily complete set tasks/goals for clients. I usually set up entire product lines and...

mcgyvr: Thanks. Regarding the codes (for car locks) do you know if they're available, and how tough it would be to get them? As far as I know, thiefs would have no use for these codes, since it takes a 2nd key to program it. MiketheEngineer: Sorry, what do you mean? Your Ford came with a...

IRStuff You are correct, I know nothing about electrical engineering and electronic car keys. The product I am working on is not your typical electric keyfob. A USB port, or other form of connection to a computer, could theoretically be added, if needed, to program the remote to work with a...

I am trying to create a universal remote. I understand that each car manufacturer uses a different frequency / codes. Could user plug it into their PC and download the appropriate data? Or is this not something that can be simply programmed?

Hello all, I am an Industrial Designer, I design consumer products for a living. Sorry my questions may appear silly! I am working on a small remote for car locks for a client. Users need to be able to program it (the same way one programs a 2nd set of car keys, by pushing buttons at correct...
