Question about Car Audio & Video

3 Answers

I have a new Toyota with a remote starter. The problem is that the range is only 80 feet and I need much more than that. I know that there are various tricks to increase distance slightly but they are not sufficient for my purposes. It seems to me that a repeater/amplifier might solve my problem. Since the device would live in my office, it does not have to be portable. I wonder if cell phone repeaters or other cell phone reception enhancing products might work?

    The response that I got was worthless. I have a factory remote start not the aftermarket unit that is advertised on the video. Furthermore, I don't want to start my car or check on it from across the country. I simply want to start it from a couple hundred yards away -- in the parking lot that I can see from my office.

    The reply that I got was nonsense. I already knew about this product.

  • chrisp959 Dec 12, 2009

    The battery is not the problem, nor is the antenna. The question is: How do I boost the distance. Can I use some gadget that I can buy or make such as a repeater? If so, what is the gadget? Can a cell phone booster be used?

    Is there some trick that I can use with an external antenna in my office?

    I know that I can replace the unit. However, since the car has a "smart key", this involves spending $500 - 700 and I would like to avoid doing this.

    Thank you, that's what I was looking for. Now I can figure out how to amplify it.

No i am affraid a cell phone
enhancing product won't work. they are different fm and cell.

I suggest going directly to the battery for power and ground. Also, placement of the antenna is critical, it should be placed high on the glass- like centered on the windshield above the rear view mirror. If you have tinted windows, metallic tint will affect your range as well. If you've noticed your range decrease recently, try replacing the battery in your remote.
If all else fails, you can always upgrade.
If you have good antenna placement and a good battery in your remote, you may be at your maximum usable range. Note that I used the battery that came with my last remotestart/alarm/keyless for a year, then replaced it. After replacing it I noticed the range almost doubled, maybe the other battery was just cheap? Maybe it had been sitting in storage for a few years? In short, if your connections are good and the install is done properly you may just have to live with this.

you can try this http://www.crutchfield.com/S-vRZu4gTzbfP/cgi-bin/prodview.asp?i=514AUANT

but the range should be atleast 200ft. not 80ft. 80 means you are near interference or there is a big issue. hth

    totaly understand your pain and i did provide you with the anwsers you just didn't read them. first you can not use a cell phone booster because they transmit different signal totaly. on a range booster it will need to be correct for your system and because it is factory witch you never stated it will be hard to find. now if you only get 80ft. there is an issue and reason for getting so low of a range and will need to be looked at because theres an issue and a range booster is a band aid and will most likely bare no results.

    take it to the dealer because it is their unit and will be best to get the info to repair correctly.

    let me know if you have any more question and sorry for your frustration in this and i hope you make out

    If you hold the remote start key fob up to and touching your chin,
    press the button(s) while looking at you vehicle, you can extend the
    distance at which the remote will work. Your body acts as an attenna
    extending the power of the remote. I kid you you not. Try it, it works.

    hi again i have been doing research all day and the factory units stink because the use the factory remore and the range on them are made for close distances not long range. now if you want help like i have said and i am sure other have said you will need to replace the unit with an aftermarket one to get the range you desire.

    in order to get a booster you will need to know what freq. the remote is transmitting on and when you figure that out you then can get a range booster or see if they make a range booster for that freq.


    To verify the frequency of your remote, open the casing and look at the writing on the quartz. You can't go wrong!

    Photos of the quartz with the frequencies written on are attached to
    the product information of the remotes that could look identical but
    have different frequencies.

    In certain remotes, the frequencies are not easily visible. You should
    therefore look at the back of the remote, or in your receiver.
    Attention, frequencies (MHz) are figures like 30.875 or 26.995 or
    433.920, etc. Numbers beginning “CE...” on the back of a remote are not
    frequencies. The other numbers written on the quartz (such as “MEC...”)
    are also useless in determining frequency.

You do not say how much more range you need. If you are talking about double your existing range that may be possible but if you are talking about triple or more that just may be impossible with the OEM unit. If you can find the antenna and make it allot longer and mounted higher, than the stock antenna it will increase the range. How much is impossible to say. A repeater would have to be mounted somewhere between you and the vehicle so I really do not see how that would work for you. Unless that repeater was really powerful and could be mounted in your office. You would also need a repeater that emulates the frequency of the remote. I know this is probably of no help to you but it is all I have. Good luck and I hope you figure this out.

U could do this, but you will need to figure out the frequency of the remote to do it and then find a suitable repeater, there are remote starters that can use a cell phone repeater signal to start the car, it is called a JayCar SMS Controller, contact any auto electronics installation and sales service for details on this cell phone activated remote starts system, this really the only viable option.

I just purchased a viper 5902 remote start/ alarm for my 2010 toyota corolla sport and dont know what bypass i need to buy.


Well, that depends on which type of key you have. Is it a smart key, a 40 bit encryption key or an 80 bit encryption key? The DBALL or the FLCAN will work on the smart key. The DBALL, PKALL, FLTB1 and FLCAN will work on the 40 bit key. A word of advice: if your vehicle has the 80 bit key, use your valet key and a universal key box to bypass the immobilizer for the remote starter. Finding the the IMI/IMO wires in this vehicle can be tricky and time consuming.
You can tell the differnce in the keys by looking at the metal stem. If a dot is present, it's a 40 bit. If a G is present , it's an 80 bit.

I want to install Toyota OEM remote starter to my 2009 Venza with factory installed push button starter and factory alarm. Any recommendations for installation guide or video?


Do not install the OEM starter - it only works from about 80 feet away and is quite problematic. I just purchased a new V6-AWD with the push button start and the dealer is taking the OEM start out as we speak and taking it for an after market starter.

If you decide to do it yourself (you'll need to be quite mechanically inclined for this install), check youtube as the poster above has suggested - but again I highly suggest you consider an aftermarket starter and save the money that I didn't.

Remote start will work intermittently. have tried from 10 feet to 50 feet with same results. won't start. went to dealer they stated its because the range is not too high for the factory installed system....


Have you changed the battery in the remote?

Do so, then re-introduce the remote to the remote start system following the manufacturer's instructions, and the problem should be solved.

Increase range for remote starter on 2007 grand prix


Try changing the battery in the key fog. If that doesn't work you can try finding an aftermarket key fog with a greater range. It is probably just default range.

No range for my Bulldog Remote Start.


Get a Viper 5900, it has a 1 mile + range
Or a viper 5601 has a 2000 ft range.

Bulldog is DIY and entry level stuff. You cant expect much from them.

The wire antennas work the best when they are stretched out. Not wadded in a ball or in a loop. If you have to loop it use figure 8's. Try streatching it up the "A" pillar and in the headliner across the top of the windshield. Also, do not ground the antenna, and let the end hang.

Also check your hot and ground connections. Make your ground at the kick panel sheet metal. Do not use a factory ground or a metal bracket in the dashboard. Do use a file or sandpaper to buff the ground site to the bare metal.
